simplify e^{-7y}cos(2x)

Solution

simplify

e^{- 7 y} cos (2 x)

Solution

\frac{cos ( 2 x )}{e ^{7 y}}

Solution steps

e^{- 7 y} cos (2 x)

Apply exponent rule:

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

= \frac{1}{e ^{7 y}} cos (2 x)

Multiply fractions:

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

= \frac{1 \cdot cos ( 2 x )}{e ^{7 y}}

Multiply:

1 \cdot cos (2 x) = cos (2 x)

= \frac{cos ( 2 x )}{e ^{7 y}}
