simplify e^{-2y}*4y

Solution

simplify

e^{- 2 y} \cdot 4 y

\frac{4 y}{e ^{2 y}}

Solution steps

e^{- 2 y} \cdot 4 y

Apply exponent rule:

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

= 4 \cdot \frac{1}{e ^{2 y}} y

Multiply fractions:

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

= \frac{1 \cdot 4 y}{e ^{2 y}}

Multiply the numbers:

1 \cdot 4 = 4

= \frac{4 y}{e ^{2 y}}

4 e^{- 0.65 \cdot 8}

2500 (1 + 0.07)^{- 7}

e^{- 4.67}

50 e^{- 0.05268 \cdot 2}
