(z)^3 = (1*z)^3 (z)^3 = (1)^3*(z)^3 (z)^3 = 1*z^3 (z)^3 = z^3

think of z^3*3z^4 as 1z^3*3z^4

z^3 times z^4 = z^(3+4) = z^7 so the final answer is 3z^7

does exponents distribute first? if so, does the ^3 distribute to the 5 as well or just the (x^2z^6)?

the exponent of 3 only applies to terms inside the parenthesis

so (x^2z^6)^3 means you cube x^2 and z^6
