simplify e^{-t}cos(h)2t

simplify

e^{- t} cos (h) 2 t

\frac{2 t cos ( h )}{e ^{t}}

Solution steps

e^{- t} cos (h) \cdot 2 t

Apply exponent rule:

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

= 2 \cdot \frac{1}{e ^{t}} t cos (h)

Multiply fractions:

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

= \frac{1 \cdot cos ( h ) \cdot 2 t}{e ^{t}}

Multiply the numbers:

1 \cdot 2 = 2

= \frac{2 t cos ( h )}{e ^{t}}

- x^{3} (x - 4)^{2} (x + 2)^{2}

x + x + 1 \cdot x + x - 1

\frac{x ^{2} + 1}{x ^{2} - 1}

\frac{36}{- 49}

(b^{\frac{2}{3}} \cdot c^{\frac{2}{5}}) (b^{\frac{4}{9}} \cdot c^{\frac{9}{10}})
