\frac{1}{2}

+1

Decimal Notation

0.5

Solution steps

4^{- \frac{1}{2}}

Factor the number:

4 = 2^{2}

= (2^{2})^{- \frac{1}{2}}

Apply exponent rule:

(a^{b})^{c} = a^{b c}, a \geq 0

= 2^{2 (- \frac{1}{2})}

2 (- \frac{1}{2}) = - 1

= 2^{- 1}

Apply exponent rule:

a^{- 1} = \frac{1}{a}

2^{- 1} = \frac{1}{2}

= \frac{1}{2}
