I need help with both questions.

Answer:
15 and 270
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{a}[/tex] = a
[tex]\sqrt[3]{a}[/tex] × [tex]\sqrt[3]{a}[/tex] × [tex]\sqrt[3]{a}[/tex] = a
(a)
Given
([tex]\sqrt{5}[/tex] )² × ([tex]\sqrt{3}[/tex] )²
= 5 × 3
= 15
(b)
Given
([tex]\sqrt[3]{9}[/tex] )³ × ([tex]\sqrt{30}[/tex] )²
= 9 × 30
= 270
