A sloth moves along a tree at 3^-1 m each minute. How long will it take a sloth to climb a tree that is 33 m tall?
Having a negative exponent means that your nominator and denominator flip, and the exponent stays with the number it was with. (ie 2-3 = 1/23)
Since the exponent is only a power of 1, this becomes a fairly easy problem
33 = x/3
