simplify-2e^{-x}e^{-x}

simplify

- 2 e^{- x} e^{- x}

- 2 e^{- 2 x}

Solution steps

- 2 e^{- x} e^{- x}

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

e^{- x} e^{- x} = e^{- x - x}

= - 2 e^{- x - x}

Add similar elements:

- x - x = - 2 x

= - 2 e^{- 2 x}

- 10 a^{2} (3 a)

\frac{x - 3}{x + 2}

e^{- t} sin (wt)

2 e^{2 x} \cdot 4 e^{2 x}

4 (3.14) (4)^{2}
