Well you're contradicting yourself. you're saying a isnt right but saying the "81's right" and a includes 81.

Answer 7

What does 3^4 equal?

No i was saying 81's right because you said there are some that are obviously not right so i was responding to that :) and 3^4 Equals 81

But isnt this saying (3x)^4

Answer 10

yes,and you can distribute the power to both terms. \((3x)(3x)(3x)(3x) = 3^4 \cdot x^4\)
