please helppp :)))))))) im genuinely confused

Answer:
[tex]$ y^{\frac{2}{3}} $[/tex] is the answer.
Step-by-step explanation:
According to the power rule, we have:
[tex]$ (a^b)^c = a^{b.c} $[/tex]
We use the power rule to solve the problem.
Therefore, [tex]$ \bigg( y^\frac{2}{15} \bigg ) ^5
= \bigg(y^\frac{2.5}{15}\bigg)
= \bigg(y^\frac{2}{3}\bigg)$[/tex] which is the required answer.
