Answer 1

The rule for division of exponents is \[\frac{ x^a }{ x^b }=x^{(a-b)}\]. The answer using this rule is x^30

Answer 2

??

Answer 3

3^50 ÷ 3^20 = 3^(50 - 20) = 3^30

You might think of it as 3 x 3 x 3 x 3 (fifty times) divided by 3 x 3 x 3 x 3 (twenty times).

A whole bunch of the three's (top and bottom) are going to cancel out. Try it on a scrap of paper. :)
