36.
It is: 4 times 81/9 = 36
81 can be divided by 9 nine times. 9/81 = 1/9 (9 x 9 = 81)
The greatest common factor between 36 and 81 is 9. 36/9 = 4 and 81/9 = 9.36/81 = 4/9.
√(16/81) = (√16)/(√81) = 4/9 → The two roots are 4/9 and -4/9
(4/9) * (5/9) = 20/81
It is: 4 times 81/9 = 36
81 can be divided by 9 nine times. 9/81 = 1/9 (9 x 9 = 81)
81/4
The greatest common factor between 36 and 81 is 9. 36/9 = 4 and 81/9 = 9.36/81 = 4/9.
√(16/81) = (√16)/(√81) = 4/9 → The two roots are 4/9 and -4/9
(4/9) * (5/9) = 20/81
9/100 x 10/81 is 1/90
sqrt(4/81) = sqrt(4)/sqrt(81) = 2/9

25/81 simplified
How about: 9 times 9 = 81 or 81 times 1 = 81
You can express 81 as a power in several ways: ( 81 = 3^4 ) because ( 3 \times 3 \times 3 \times 3 = 81 ). ( 81 = 9^2 ) since ( 9 \times 9 = 81 ) and ( 9 ) can be rewritten as ( 3^2 ). ( 81 = (3^2)^2 ) which simplifies to ( 3^{2 \times 2} = 3^4 ). Thus, all representations confirm that ( 81 ) can be expressed as a power in different forms.
