simplify (e^{-2y})/(e^{-y)}

Solution

simplify

\frac{e ^{- 2 y}}{e ^{- y}}

Solution

e^{- y}

Solution steps

\frac{e ^{- 2 y}}{e ^{- y}}

Apply exponent rule:

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

= e^{- 2 y - (- y)}

Apply rule

- (- a) = a

= e^{- 2 y + y}

Add similar elements:

- 2 y + y = - y

= e^{- y}
