3 to the power of 4 = 81
± 3 to the fourth power equals 81.
3^(-2x + 2) = 81? log(3^(-2x + 2)) = log(81) (-2x+2)log(3) = log(81) -2x = log(81)/log(3) - 2 x = (-1/2)(log(81)/log(3)) + 1

3/9 = x/81 x = 27 So: 3/9 = 27/81
34 = 81
Notice that 243 is 3 to the 5th power.So your equation says:3x = 35I'd say that 'x' is probably 5.
3^(-4) = (1/3)^4 = 1/81
Its 3 to the fourth power. Is that what you're asking?
3 to the fourth power=81Three to the fourth power is 81.
