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

divide that exponent by 2 and you are all set

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

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

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

OpenStudy (anonymous):

yeah

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

OpenStudy (anonymous):

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

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

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

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.
