9x9=81
You calculated by doing 81 divided 4, it will equal 20.25
9x+27 = -81 9x = -81-27 9x = -108 x = -12
log9(x)=2 x=9^2 x=81
X = 81 sqrt(X) + 3 = 12 ( subtract 3 from each side ) sqrt(X) = 9 (square both sides ) X = 81 ( the square root of 81 is 9 )
y3 x y3 - y (3)3 x 3(3) - 3 9 x 9 - 3 = ? 9 x 9= 81 81 - 3 = 78 I hope that solves your problem
3.14 x 81 = 254.34
If: x2 = 81 Then: x = 9 or x = -9
81 = 35 * x so x = 81/35 which cannot be simplified further.
81 x 81 = 6561
81 x 58 = 4698
1 x 81, 3 x 27, 9 x 9, 27 x 3, 81 x 1
x: x2 - 81 = 0
3x=81 3x/3=81/3x=27
9 X 9 = 81
34 = 81 so x is 4
1-10x = 81 -10x = 81-1 -10x = 80 x = -8
3/9 = x/81 x = 27 So: 3/9 = 27/81
27 x 3 = 81
