The square roots of -81 are ±9i where i is the imaginary square root of -1.
With square roots if you have a number times itself or squared then that that product is that numbers square root example: 9x9= 81 81 square root is 9
√(16/81) = (√16)/(√81) = 4/9 → The two roots are 4/9 and -4/9
The square roots of 81 are -9 and +9.

Nine :) * * * * * Sort of. ± 9 are the square roots (not rout!) of 400.
While it is true that 9/10 x 9/10 = 81/100, fractions do not have square roots.
yaa but im tryna find out why
