Evaluate (125/8)^(2/3)

${(\frac{125}{8})}^{\frac{2}{3}}$

Step 1

Apply the product rule to $\frac{125}{8}$ .

$\frac{125^{\frac{2}{3}}}{8^{\frac{2}{3}}}$

Step 2

Simplify the numerator.

Rewrite $125$ as $5^{3}$ .

$\frac{{(5^{3})}^{\frac{2}{3}}}{8^{\frac{2}{3}}}$

Apply the power rule and multiply exponents, ${(a^{m})}^{n} = a^{m n}$ .

$\frac{5^{3 (\frac{2}{3})}}{8^{\frac{2}{3}}}$

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{5^{3 (\frac{2}{3})}}{8^{\frac{2}{3}}}$

Rewrite the expression.

$\frac{5^{2}}{8^{\frac{2}{3}}}$

Raise $5$ to the power of $2$ .

$\frac{25}{8^{\frac{2}{3}}}$

Step 3

Simplify the denominator.

Rewrite $8$ as $2^{3}$ .

$\frac{25}{{(2^{3})}^{\frac{2}{3}}}$

Apply the power rule and multiply exponents, ${(a^{m})}^{n} = a^{m n}$ .

$\frac{25}{2^{3 (\frac{2}{3})}}$

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{25}{2^{3 (\frac{2}{3})}}$

Rewrite the expression.

$\frac{25}{2^{2}}$

Raise $2$ to the power of $2$ .

$\frac{25}{4}$
