125

Explanation:

I'll assume you mean
#(5*sqrt(5))^2#

Since it is a multiplication inside the parentheses,
removing the parentheses gives you:
#5^2 (sqrt(5))^2#

So, #5^2=25#, right?
And #(sqrt(5))^2=5# (it's the square of a square-root, so yeah)
Then you are left with:
#25*5=125#

That's it! Hope it helped.
