Question

Rewrite with positive exponents, and simplify, if possible. 9x/7^√y

Answer 1

\[9x/7^\sqrt{y}\]
is that the expression?

Answer 2

\[9x / \sqrt[7]{y}]

Answer 3

idk if i wrote that last one right but it is a little 7

Answer 4

\[9x/\sqrt{7y}\]
This?

Answer 5

or:
\[9x/\sqrt[7]{y}\]

Answer 6

no everything is correct but it is a little 7 on top of the check

Answer 7

\[\frac{9x}{\sqrt[7]{y}}\]

Answer 8

yes thats it

Answer 9

I'm not exactly sure what this question is asking, except perhaps that they want you to change \[\sqrt[7]{y}\]
into exponent form.

When you have the square root, you can rewrite it in exponent form like this:
\[\sqrt[2]{y} = y ^{1/2}\]
And when you take the inverse of an exponent, you change the sign on the exponent:
\[1 / y ^{1/2} = y ^{-1/2}\]

So you can convert \[\sqrt[7]{y}\] into an exponent. Perhaps that's all?

Answer 10

I don't think thats right. the answer choices i have are 9xy^1/7 or 9x/y^7 or 9xy^7 or 9x/y^1/7

Answer 11

Ok, so just do the first thing -- convert \[\sqrt[7]{y}\] into an exponent like I did the example of \[\sqrt[2]{y}=y ^{1/2}\]
