Evaluate (81)^(3/2)

${(81)}^{\frac{3}{2}}$

Step 1

Simplify the expression.

Rewrite $81$ as $9^{2}$ .

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

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

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

Step 2

Cancel the common factor of $2$ .

Cancel the common factor.

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

Rewrite the expression.

$9^{3}$

Step 3

Raise $9$ to the power of $3$ .

$729$
