Answer:
When dealing with radicals and exponents, one must realize that fractional exponents deals directly with radicals. In that sense, sqrt(x) = x^½. In a fractional exponent, the numerator represents the actual exponent of the number. So, for x^2/3, the x is being squared.For the denominator, that deals with the radical. The index, to be exact. The index describes what kind of radical (or root) is being taken: square, cube, fourth, fifth, and so on. So, for our example x^2/3, x is squared, and that quantity is under a cube root (or a radical with a 3).^^^Exponential fractions still follow the same rules of simplifying, so...
x^2/4 = x^1/2 = sqrt(x)
Step-by-step explanation:
When dealing with radicals and exponents, one must realize that fractional exponents deals directly with radicals. In that sense, sqrt(x) = x^1/2
Now, how to go about doing this:
In a fractional exponent, the numerator represents the actual exponent of the number. So, for x^2/3, the x is being squared.
For the denominator, that deals with the radical. The index, to be exact. The index describes what KIND of radical (or root) is being taken: square, cube, fourth, fifth, and so on. So, for our example x^2/3, x is squared, and that quantity is under a cube root (or a radical with a 3). Here are some more examples to help you understand a bit more:
x^6/5 = Fifth root of x^6
x^3/1 = x^3
^^^Exponential fractions still follow the same rules of simplifying, so...
x^2/4 = x^1/2 = sqrt(x)

Step-by-step explanation:
1 * w^3
how do you multiply these together
9514 1404 393
Answer:
w^3
Step-by-step explanation:
The multiplicative identity element is 1. That means 1 times anything is just that thing.
1 × w^3 = w^3
_____
Additional comment
That is one of the reasons why a coefficient of 1 is (almost) never shown.
In algebra, multiplication can be indicated a number of ways.
ab . . . . placing values next to each other (sometimes with a small space)
(a)(b) . . . . placing values next to each other with either or both in parentheses
a·b . . . . . using a multiplication symbol between the values.
There are several different multiplication symbols in common use:
* — asterisk
· or • — centered dot
× — centered "x" multiplication symbol
x — the lower-case letter x (when it cannot be confused with a variable)
. — a period (when it cannot be confused with a decimal point). This is uncommon in the US, but is seen occasionally when some of the other symbols are not available. It is more common outside the US.
_____
The multiplication of a constant and a variable expression cannot actually be accomplished. It can only be "indicated." If you wanted to multiply 2*w^3, that product would be indicated in any of the ways described above. Perhaps the simplest and least-confusing to most people is ...
2w^3
Multiplying 1*w^3 can be indicated the same way: 1*w^3. In view of the special treatment given to a coefficient of 1, we would not simplify this to
1w^3
Rather, we would simplify it to ...
w^3

25 hours this week but printed books twice the hourly rate of the first machine. How many books did the
second machine print this week?
Answer:
875 books
Step-by-step explanation:
1st machine 700 books/40 hours = 17.5 books/hr
2nd machine printed 2x or 35 books/hr
25 hours x 35 books/hr = 875 books

Which equation describes a relationship such that x = 0 must be excluded from the domain?
Answer:
Example: f(x) = (1 + x + x^2) / x, x=0 is excluded from the domain, since division by zero is undefined.

The area of the table should be
10 ft2. You want the length of the table to be 1 ft shorter than twice its width.
What should the dimensions of the table be?
Answer: width : 2.5 ft. and length : 4 ft.
Step-by-step explanation:
The area = W × L
[tex]10=W(2W-1)[/tex]
[tex]10=2W^{2} -W[/tex]
[tex]0 = 2W^{2}-W-10[/tex]
[tex]0=(2W-5)(W+2)[/tex]
W = 2.5 and -2
You can't use -2 so
[tex]L = 2(2.5)-1[/tex]

At its peak, an online shopping site was selling about 420 items per second. At this rate, how many items would it sell in 30 minutes ( 1,800 seconds)?
Answer: 758,000
Step-by-step explanation:
Expression: 420 x 1,800
Basically just find the number of seconds and since every second 420 items are sold just multiply 420 x number of seconds which is 1,800

16. A craft shop sold 150 pillows. Small pillows were $6.50 each and large pillows were $9.00 each. If the total amount collected from the sale of these items was $1180.00, what is the total number of each size pillow that was
sold?
Answer:
82 large pillows, 68 small pillows
Step-by-step explanation:
Suppose all pillows sold were small pillows:
150×$6.50=$975
$1180-$975=$205
$9-$6.50=$2.50
$205÷$2.50=82 (no of large pillows sold)
No. of small pillows sold
=150-82

The length of a marathon race is 26 miles 385 yards. What is the total length of the marathon
race in yards?
Plz help
Answer:
46,145
Step-by-step explanation:
26x1760= 45,760 + 385= 46,145
The total length of the marathon race in yards when the length of a marathon race is 26 miles 385 yards, is 46145 yards.
How to measure the length?Length measurement is the measurement of the size of an object. The units of length measurement are meter, feet, yards etc.
Yards-This unit is used when the size of a small space has to measure, such as length of bed, ladder etc. There are total 1760 yards in one mile.Miles-This is the basic unit of length measurement of size. The size of roads, distance between two cities are measured in miles.The length of a marathon race is 26 miles 385 yards. As there are total 1760 yards in one mile. Thus, the total number of yards in 26 miles is,
[tex]26\times1760=45760[/tex]
Now, he races for 385 yards along with 26 miles. Thus, the length of marathon is,
[tex]45760+385=46145\rm\; yards[/tex]
Thus, the total length of the marathon race in yards when the length of a marathon race is 26 miles 385 yards, is 46145 yards.
