9x9=81
3.14 x 81 = 254.34
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 )
9x+27 = -81 9x = -81-27 9x = -108 x = -12
log9(x)=2 x=9^2 x=81
81(a^4)
mean = (4 + 81)/2 = 85/2 = 42.5
81 x 4 - 1 = 323
√16 x √81 = 4 x 9 = 36
1/81 one over 81 The answer is the fraction 1/81.
log3(x)=4 x=3^4 x=81
log37 - log3x = 4 log3(7/x) = 4 7/x = 34 = 81 x = 7/81

Prime FACTORIZATION of 81: 3^4
That equation can not be factored. It can however be solved for x: x2 - 9x + 4 = 0 x2 - 9x + 81/4 = 81/4 - 4 (x - 9/2)2 = 81/4 - 16/4 (x - 9/2)2 = 65/4 x - 9/2 = ± √65 / 2 x = (9 ± √65) / 2
