Question

Find the value of 7 times x squared all over the square root of x to the fifth power.

7 times the square root of x, all over x.
7 over x.
7 times the square root of x.
7 times x all over the square root of x.

Answer 1

Alright, so we start with 7x^2/sqrt(x)^5

This can be simplified to 7x^2/x^(5/2)
Then, separate the denominator to x^2*x^(1/2)
You can then cancel out the x^2 in the numerator and the x^2 in the denominator, leaving you with x^(1/2) which is the same thing as sort(x)
So, the final answer should be 7/sqrt(x)

Answer 2

So which choice would that be?

Answer 3

NEw best answer for who answers

Answer 4

Any takers?

Answer 5

got the answer of 7/sqrt(x). from the choices, what do you think would equal this when simplified?

Answer 6

just 7 over x?

Answer 7

or is that the answer?? i got 7 over x i just don't know if that is right

Answer 8

what happens when you have x^(1/2)/x ?

Answer 9

It stays the same

Answer 10

no. you get 1/(x^(1/2))
because (1/2)[from the numerator] - 1[from the denominator] = -1/2

x^(-1/2) = 1/(x^(1/2))

Answer 11

so what would be the wording for that?

Answer 12

Oh okayyy so the final answer is 7/sqrt(x)?

Answer 13

yes. just like what trogdortheburninator said. but i assume we are looking for the answer in sentence form. so that would be the first.

Answer 14

okay thank you so much!

Answer 15

I am about to put another one up can you walk me through it?
