Solution

simplify

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

Solution

\frac{1}{7}

+1

Decimal Notation

0.37796 \dots

Solution steps

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

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

= 7^{- \frac{1}{2}}

Apply exponent rule:

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

7^{- \frac{1}{2}} = \frac{1}{7 ^{\frac{1}{2}}}

= \frac{1}{7 ^{\frac{1}{2}}}

Apply exponent rule:

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

7^{\frac{1}{2}} = 7

= \frac{1}{7}
