Answer 1

$\huge{ \underline{ \boxed{ \mathfrak{ \red{question}}}}}$

$a) {8}^{ \frac{ - 1}{3} } \times \sqrt[3]{8} \\ b) {3}^{ \frac{2}{3} } \times {3}^{ \frac{1}{3} }$

$\huge{ \underline{ \boxed{ \mathfrak{ \red{answer}}}}} \\ \\ a) {8}^{ \frac{ - 1}{3} } \times \sqrt[3]{8} \\ \\ = > {8}^{ \frac{ - 1}{3} } \times {8}^{ \frac{ 1}{3} } \\ \\ base \: same \: power \: add \\ \\ = > {8}^{ \frac{ - 1}{3} + \frac{1}{3} } \\ \\ = > {8}^{ \frac{ - 1 + 1}{3} } \\ \\ = > {8}^{ \frac{0}{3} } \\ \\ {8}^{0} \\ \\ = > 1$

$b). {3}^{ \frac{2}{3} } \times {3}^{ \frac{1}{3} } \\ \\ = > base \: same \: power \: add \\ \\ = > {3}^{ \frac{2}{3} + \frac{1}{3} } \\ \\ = > {3}^{ \frac{2 + 1}{3} } \\ \\ = > {3}^{ \frac{3}{3} } \\ \\ = > {3}^{ \frac{1}{1} } \\ \\ = > {3}^{1} \\ \\ = > 3$
