Both of those numbers are perfect squares, so square root each number separately and you will get your answer.
√(81/100) = √81 / √100 = 9/10 = 0.9
Don't know how far you've progressed as technically the answer is ± 0.9, but you may not have reached the stage of dealing with negative square roots of positive numbers.
It is -10/9
The square root of 81 is 9 and the square root of 4 is 2!
sqrt(4/81) = sqrt(4)/sqrt(81) = 2/9
Square root of 81
The opposite of a square root is the square of a number. For example, the principal square root of 81 is 9, while the square of 9 is 81.
It is -10/9
No. The square root of 81/(-3) is rational. The square root of [81/(-3)] is imaginary (a kind of complex number).
When 100 is squared, the root is 10. That means you can multiply 10 by 10 and the answer is 100. The square root of 81 is 9 and 8 is the square root of 64.
81 is the square root and 9.5 is under root.
sqrt(25/81) = 5/9
The square root of -81 = 9 i9i
The square root of -81 = 9 i9i
The square root of 81 is 9
The square root of 6561 is 81
The square root of 81 is 9 and the square root of 4 is 2!
9/8
It is: 5/9
