simplify e^{-x}(-e^{-y}+1)

Solution

simplify

e^{- x} (- e^{- y} + 1)

Solution

\frac{- e ^{- y} + 1}{e ^{x}}

Solution steps

e^{- x} (- e^{- y} + 1)

Apply exponent rule:

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

= \frac{1}{e ^{x}} (- e^{- y} + 1)

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 \cdot ( - e ^{- y} + 1 )}{e ^{x}}

1 \cdot (- e^{- y} + 1) = - e^{- y} + 1

= \frac{- e ^{- y} + 1}{e ^{x}}
