simplify-8e^{-x}cos(x)

simplify

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

- \frac{8 cos ( x )}{e ^{x}}

Solution steps

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

Apply exponent rule:

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

= - 8 \cdot \frac{1}{e ^{x}} cos (x)

Multiply fractions:

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

= - \frac{1 \cdot 8 cos ( x )}{e ^{x}}

Multiply the numbers:

1 \cdot 8 = 8

= - \frac{8 cos ( x )}{e ^{x}}

(3.1 \cdot 1 0^{4}) (4.264 \cdot 1 0^{- 3})

x - 1 \times x + 1

68.7 (e^{345 + 25})^{- 1}
