160 e^{- 2 x}

Solution steps

(8 e^{- x}) (20 e^{- x})

Apply exponent rule:

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

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

= 8 \cdot 20 e^{- x - x}

Add similar elements:

- x - x = - 2 x

= 8 \cdot 20 e^{- 2 x}

Multiply the numbers:

8 \cdot 20 = 160

= 160 e^{- 2 x}

2 a + x \cdot a - x

2 (2 a^{2} b)

- 6 e^{- 3 t} \cdot 18 e^{- 3 t}

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

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