Evaluate (1/8)^(2/3)

${(\frac{1}{8})}^{\frac{2}{3}}$

Step 1

Simplify the expression.

Apply the product rule to $\frac{1}{8}$ .

$\frac{1^{\frac{2}{3}}}{8^{\frac{2}{3}}}$

One to any power is one.

$\frac{1}{8^{\frac{2}{3}}}$

Step 2

Simplify the denominator.

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

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

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

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

Cancel the common factor of $3$ .

Cancel the common factor.

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

Rewrite the expression.

$\frac{1}{2^{2}}$

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

$\frac{1}{4}$

Step 3

The result can be shown in multiple forms.

Exact Form:

$\frac{1}{4}$

Decimal Form:

$0.25$
