Evaluate (-3/2)^3

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

Step 1

Use the power rule ${(a b)}^{n} = a^{n} b^{n}$ to distribute the exponent.

Apply the product rule to $- \frac{3}{2}$ .

${(- 1)}^{3} {(\frac{3}{2})}^{3}$

Apply the product rule to $\frac{3}{2}$ .

${(- 1)}^{3} \frac{3^{3}}{2^{3}}$

Step 2

Raise $- 1$ to the power of $3$ .

$- \frac{3^{3}}{2^{3}}$

Step 3

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

$- \frac{27}{2^{3}}$

Step 4

Raise $2$ to the power of $3$ .

$- \frac{27}{8}$
