simplify-cos(e^x)e^{-x}

simplify

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

- \frac{cos ( e ^{x} )}{e ^{x}}

Solution steps

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

Apply exponent rule:

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

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

Multiply fractions:

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

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

Multiply:

1 \cdot cos (e^{x}) = cos (e^{x})

= - \frac{cos ( e ^{x} )}{e ^{x}}

e^{- 10 k}

2^{x} 3^{x}

7.8 (20)^{- 0.5}

55.76 \cdot 1 0^{- 9} \cdot 1
