What is the square root of 64 over 225 with a negative outside of the radical?
1 answer:
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 = <em>8 / 15</em> . Oh, I almost forgot, it has a negative sign before it. OK,so the answer is <em>- 8/15</em> .
