Evaluate (64/9)^(3/2)

${(\frac{64}{9})}^{\frac{3}{2}}$

Step 1

Apply the product rule to $\frac{64}{9}$ .

$\frac{64^{\frac{3}{2}}}{9^{\frac{3}{2}}}$

Step 2

Simplify the numerator.

Rewrite $64$ as $8^{2}$ .

$\frac{{(8^{2})}^{\frac{3}{2}}}{9^{\frac{3}{2}}}$

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

$\frac{8^{2 (\frac{3}{2})}}{9^{\frac{3}{2}}}$

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{8^{2 (\frac{3}{2})}}{9^{\frac{3}{2}}}$

Rewrite the expression.

$\frac{8^{3}}{9^{\frac{3}{2}}}$

Raise $8$ to the power of $3$ .

$\frac{512}{9^{\frac{3}{2}}}$

Step 3

Simplify the denominator.

Rewrite $9$ as $3^{2}$ .

$\frac{512}{{(3^{2})}^{\frac{3}{2}}}$

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

$\frac{512}{3^{2 (\frac{3}{2})}}$

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{512}{3^{2 (\frac{3}{2})}}$

Rewrite the expression.

$\frac{512}{3^{3}}$

Raise $3$ to the power of $3$ .

$\frac{512}{27}$
