1 x 81, 3 x 27, 9 x 9, 27 x 3, 81 x 1
Whole numbers between 10 and 100 using the digits 3, 1, and 8 are:13, 18, 31, 38, 81, and 83.13, 18, 31, 38, 81 and 83.
It is 12 and 2/3rds. What you do is set 38 over 1, so you are multiplying 1/3 times 38/1. That equals 38/3. Reduce it and get 12 and 2/3rd. Or 12.6
3 to the power of 4 = 81
It is: 114/3 = 38
-1 × 81 -3 × 27 -9 × 9 -27 × 3 -81 × 1
1/3 = 27/81
1 x 81, 3 x 27, 9 x 9, 27 x 3, 81 x 1
2 x 19 = 38 3 x 3 x 3 x 3 = 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
