simplify 16^{-1/2}

Solution

simplify

1 6^{- \frac{1}{2}}

Solution

\frac{1}{4}

+1

Solution steps

1 6^{- \frac{1}{2}}

Factor the number:

16 = 4^{2}

= (4^{2})^{- \frac{1}{2}}

Apply exponent rule:

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

= 4^{2 (- \frac{1}{2})}

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

= 4^{- 1}

Apply exponent rule:

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

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

= \frac{1}{4}
