simplify (x^{2-b})/(x^{2+8x+15)}

simplify

\frac{x ^{2 - b}}{x ^{2 + 8 x + 15}}

x^{- 8 x - b - 15}

Solution steps

\frac{x ^{2 - b}}{x ^{2 + 8 x + 15}}

Apply exponent rule:

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

= x^{2 - b - 2 - 8 x - 15}

Simplify

2 - b - 2 - 8 x - 15 : - 8 x - b - 15

= x^{- 8 x - b - 15}

(- 1)^{79}

e^{- 3 x} (e^{- 3 x})
