What is the square root of \(\frac{64}{225}\) with a negative outside of the radical?
Answer (2)
The square root of (64/225) is the same as √64 / √225 . That could make the whole thing easier.
Do you know what either of those separate square roots is ?
You're right ! I'm so impressed!
The square root of 64 IS 8, and the square root of 225 surely is 15 . You really know your stuff !
So now, the expression is √64 / √225 = 8 / 15 .
Oh, I almost forgot, it has a negative sign before it. OK,so the answer is - 8/15 .
The square root of 225 64 is 15 8 , and with a negative sign outside the radical, the final answer is − 15 8 .
