You can probably do this one in your head:

So what you have is this:


Dividing by a fraction is the same as multiplying by its reciprocal, so you can flip every "1/25" except the first, then you replace the division symbol with a multiplication symbol. Now you have:


The first two terms cancel out and become 1, so you're left with this:

√(25^3), or √(25•25•25)

This reduces to

25√25, and as we know, √25 = 5, so

25•5 = 125.
