Answer 1

\(\bf \large {\sqrt[3]{9a}\cdot \sqrt[3]{3a^2b^3}\implies \sqrt[3]{9a\cdot 3a^2b^3}\implies \sqrt[3]{27aa^2b^3}\\ \quad \\
\color{blue}{27 \implies 3\times 3\times 3\implies 3^3\\
a\cdot a^2\implies a^1\cdot a^2\implies a^{1+2}\implies a^3}\\ \quad \\
\sqrt[3]{27aa^2b^3}\implies \sqrt[3]{3^3a^3b^3}}\)

Answer 2

as you can see, everything can come out :)

Answer 3

im deciding between a or b. can u help me please?

Answer 4

\(\bf \large \sqrt[3]{3^3a^3b^3}\implies 3ab\)

everything comes out, because every factor is raised at the same value of the root

Answer 5
