I don't understand the expression as the text you have given.

"the nth root is 4square root of 5 times the nth root is 4 square root of 5"

Is this exactly as presented in the question you were given?

i don't know how to write it....its square root of 5 with the 4 on the left side times the square root of 5 with the 4 on the left side

OK

4sqrt5 x 4 sqrt5

another way to write this (struggling with the limits of text only!) is

5^(1/4)x5^(1/4)

(^ means to the power of so 10^2=100)

or 5 to power quarter x 5 to power quarter.

When you multiply two numbers with powers together you add the powers.

e.g. 10^2 x 10^2 = 10^4

or 100^(1/2) x 100^(1/2)=100^1 (or =100)

so

5^(1/4)x5^(1/4) =?

Does this help?

Yes
