Question

howdo you evaluate the expression if the number inthe square root has an exponent?

Answer 1

divide that exponent by 2 and you are all set

Answer 2

\[\sqrt{x^{16}}= x^8\]

Answer 3

thanks (:

Answer 4

what if it has an exponent 3 befor the equation? haha sorry i dont know the right words

Answer 5

\[\sqrt{x^3}\] like this?

Answer 6

no.its right beforethe squareroot

Answer 7

\[3\sqrt{x}\]?

Answer 8

yes (:

Answer 9

Then it is as simplified as it can be.

Answer 10

so i just leave it like that?

Answer 11

Yes, Unless your problem specifically ask for something else

Answer 12

thankyou somuch! (:

Answer 13

You're welcome

Answer 14

okay.onemorequestion. the equation says ^3squareroot(n^75). so does the 3 meani just leave it alone or divide by 2?

Answer 15

\[3\sqrt{n^{75}}\]?

Answer 16

yeah

Answer 17

Try using the "Equation" button under the box where you are typing.
However, if I understood correctly, you have:
\[\sqrt[3]{n^{75}}\]

Answer 18

\[3n^{75/2}\]

Answer 19

ooh gosh, i feel dumb now. haha im new to this placde... but yeah..and thanks

Answer 20

If it is a cube root \[\sqrt[3]{n^{75}}\]
you would divide the exponent by 3
n^(75/3)

Answer 21

For future reference a square root is the same as raising to the (1/2) power
A cubed root is raising to the (1/3) power, etc.

Answer 22

thankyou guys so much! (:

Answer 23

For instance:
\[9^{0.5}=\sqrt9=3\]
