Do you mean how to find the square root of a number that is raised to an exponent?
Ex: sqrt(3^4)
Then, it would be 3 to the power of (4/2)
4 is the exponent, and 2 is because it is a square root.
So it would be 3^2, or 9

Can you provide an example with your question?
It might be easier to explain then:)

Kitty is absolutely correct. Thankyou for answering Kitty

Maybe I can help as well.

A square root is a power of 1/2

So sqrt(49) = 49^(1/2) or 49 ^ 0.5 = 7

sqrt(X) = X1/2

That is why, in Kitty's example

sqrt(3^4) = sqrt ( 3 4 ) => ( 3 4 ) 1/2 => 3 (4*1/2) => 3 2 => 9

I hope that this helps.
