Question

Find the square root of 2x2x5x5x7x7

Answer 1

You have to multiply all of them out which gives you 4,900 then you take the square root of that and your answer is 70.

Answer 2

Ohhh, look at this...

The square root of (2 x 2) is 2 .

The square root of (5 x 5) is 5 .

The square root of (7 x 7) is 7 .

So the square root of (2x2) x (5x5) x (7x7) is (2 x 5 x 7) = 70.

(It could also be -70, for reasons that we don't have to mess with right now.)
