simplify-3e^{-x}cos(x)

simplify

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

- \frac{3 cos ( x )}{e ^{x}}

Solution steps

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

Apply exponent rule:

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

= - 3 \cdot \frac{1}{e ^{x}} cos (x)

Multiply fractions:

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

= - \frac{1 \cdot 3 cos ( x )}{e ^{x}}

Multiply the numbers:

1 \cdot 3 = 3

= - \frac{3 cos ( x )}{e ^{x}}

(73)^{2}

(a^{3})^{-} 2

x e^{- l n (x)}

(x + 3) (x - 1)^{2} (x + 2)^{2}

x \cdot x^{\frac{1}{2}}
