8 and -8.

Square root 64 and square root 81

Square root of 64 and square root of 81, perhaps.

The answer depends on what you mean by higher. 81 is bigger than 64. But the square roots of 81 are -9 and +9 while the square roots of 64 are -8 and +8. You then have -9 < -8 so sqrt(81) < sqrt(64) -9 < 8 so sqrt(81) < sqrt(64) -8 < 9 so sqrt(64) < sqrt(81) 8 < 9 so sqrt(64) < sqrt(81) Take your pick!

Because both 82 and (-8)2 equal 64. So both 8 and -8 could be square roots of 64. When solving equations involves taking a square root, you need to be alert to the possibilty that there may be multiple answers.
