simplify (e^{-9t})(9cos(t))

simplify

(e^{- 9 t}) (9 cos (t))

\frac{9 cos ( t )}{e ^{9 t}}

Solution steps

(e^{- 9 t}) (9 cos (t))

Apply exponent rule:

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

= 9 \cdot \frac{1}{e ^{9 t}} cos (t)

Multiply fractions:

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

= \frac{1 \cdot 9 cos ( t )}{e ^{9 t}}

Multiply the numbers:

1 \cdot 9 = 9

= \frac{9 cos ( t )}{e ^{9 t}}

(9 \cdot 1 0^{a}) \cdot (4 \cdot 1 0^{b})

\frac{- 8}{- 4}

3^{3}

(3 s^{4})^{5} \cdot (3 s^{4})^{-} 3

(7.4 x 1 0^{6}) \cdot (2.6 x 1 0^{5})
