Evaluate (1/256)^(1/4)

${(\frac{1}{256})}^{\frac{1}{4}}$

Step 1

Simplify the expression.

Apply the product rule to $\frac{1}{256}$ .

$\frac{1^{\frac{1}{4}}}{256^{\frac{1}{4}}}$

One to any power is one.

$\frac{1}{256^{\frac{1}{4}}}$

Step 2

Simplify the denominator.

Rewrite $256$ as $4^{4}$ .

$\frac{1}{{(4^{4})}^{\frac{1}{4}}}$

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

$\frac{1}{4^{4 (\frac{1}{4})}}$

Cancel the common factor of $4$ .

Cancel the common factor.

$\frac{1}{4^{4 (\frac{1}{4})}}$

Rewrite the expression.

$\frac{1}{4^{1}}$

Evaluate the exponent.

$\frac{1}{4}$

Step 3

The result can be shown in multiple forms.

Exact Form:

$\frac{1}{4}$

Decimal Form:

$0.25$
