Answer:
Explanation:
One
√15 / ∛15 = 15^(1/2 - 1/3) = 15^(1/6)
When you divide numbers that are the same base but different powers, the following rule applies
base^(numerator power - denominator power)
Two
15^(1/2 + 1/4)
15^(3/4)
When you multiply 2 numbers with the same base and different powers you raise the base by the sum of the powers.
