The index of a number refers to the position of the number within a sequence. In this case, the index of 3x3x3x3 would depend on the sequence in which it is located. If we are considering a sequence of powers of 3 (3^1, 3^2, 3^3, 3^4, ...), then the index of 3x3x3x3 would be 3^4, which equals 81.
The index of 3x3x3x3 is 81. You just multiply all the numbers together, honey. It's not rocket science, it's basic math.
34 = 3x3x3x3
The Answer Is 81 Because 3x3=9 Then 9x3=27 Then 27x3=81 There :)
Its 3 to the fourth power. Is that what you're asking?
81 = 3^4 so 3 is a prime factor.
3x3x3x3 + 3x3x3 = 81 + 27 = 108
