simplify e^{-1/2 ln(x^2-9)}

Solution

simplify

e^{- \frac{1}{2} l n (x^{2} - 9)}

Solution

\frac{1}{x ^{2} - 9}

Solution steps

e^{- \frac{1}{2} l n (x^{2} - 9)}

Apply exponent rule:

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

= \frac{1}{e ^{\frac{1}{2} l n (x^{2} - 9)}}

e^{\frac{1}{2} l n (x^{2} - 9)} = x^{2} - 9

= \frac{1}{x ^{2} - 9}
