simplify 4te^{-t}

Solution

simplify

4 t e^{- t}

\frac{4 t}{e ^{t}}

Solution steps

4 t e^{- t}

Apply exponent rule:

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

= 4 \cdot \frac{1}{e ^{t}} t

Multiply fractions:

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

= \frac{1 \cdot 4 t}{e ^{t}}

Multiply the numbers:

1 \cdot 4 = 4

= \frac{4 t}{e ^{t}}

(3 rs t) (5 r^{7} s^{2} t^{3}) (2 r s^{3} t^{2})

- 2 x x (2 x)

- 2.18 \cdot 1 0^{- 18} \cdot 1 (\frac{1}{4 ^{2}} - \frac{1}{3 ^{2}})

1.6 (1 + \frac{x}{2.5})^{- 5}
