Power of a Product: Same base and different indicator

To simplify the given expression we use two laws of exponents:

A. The law of roots (expanded):

$\sqrt[\textcolor{blue}{n}]{a^{\textcolor{red}{m}}}=a^{\frac{\textcolor{red}{m}}{\textcolor{blue}{n}}} =(\sqrt[\textcolor{blue}{n}]{a})^{\textcolor{red}{m}}$

We continue, since multiplication is performed between two terms with identical bases - we use the law of exponents shown in B:

$2^{\frac{2}{3}}\cdot2^{\frac{1}{3}}= \\ 2^{\frac{2}{3}+\frac{1}{3}}=$

We continue and perform (separately) the operation of combining the numerators in the exponent fraction that was obtained, this is done by expanding each of the numerators to the common denominator - the number 3, then we perform the addition and subtraction operations in the numerator of the fraction:

$\frac{2}{3}+\frac{1}{3}=\\ \frac{2+1}{3}=\\ \frac{3}{3}=\\ 1$

In other words - we get that:

$2^{\frac{2}{3}+\frac{1}{3}}=\\ 2^{1}=\\ \boxed{2}$
