Explanation :

I used these steps in solving the question

I hope it helps :)

1. Note : The quotient of roots with the same indexis equal to the root of the quotient
2. Write the division as a fraction
3. Simply the expression
4. $\frac{ {a}^{8} }{ {a}^{ - 1} } = {a}^{9} \\ \frac{ {y}^{5} }{ {y}^{2} } = {y}^{3}$
5. Use the communative property to reorder the terms
6. Take the root of the numerator and denominator separately.
7. Simplify the radical expression
8. Multiply the fraction by
9. $\frac{ \sqrt[3]{ {2}^{2} } }{ \sqrt[3]{ {2}^{2} } }$
10. Calculate the product
11. Evaluate the power ( in numerator)
12. Calculate the product ( in denominator)
13. Calculate the product of 5×4u
14. Reduce the index of the radical and exponents with 3
