Answer 7

\[(3x)^{4} = (3x)(3x)(3x)(3x)\]

Answer 8

So when you evaluate that, you multiply all the 3's and you've probably learned that when you multiply consecutive x's, the powers all add up, such as: \[(x^{3})(x ^{2}) = x ^{5}\] in this respect, you can now evaluate \[(x)(x)(x)(x) \] using the same idea.
