expand 8(-0.4e^{-0.4x}+0.6e^{-0.6x})

expand

8 (- 0.4 e^{- 0.4 x} + 0.6 e^{- 0.6 x})

- 3.2 e^{- 0.4 x} + 4.8 e^{- 0.6 x}

Solution steps

8 (- 0.4 e^{- 0.4 x} + 0.6 e^{- 0.6 x})

Apply the distributive law:

a (b + c) = ab + a c

a = 8, b = - 0.4 e^{- 0.4 x}, c = 0.6 e^{- 0.6 x}

= 8 (- 0.4 e^{- 0.4 x}) + 8 \cdot 0.6 e^{- 0.6 x}

Apply minus-plus rules

+ (- a) = - a

= - 8 \cdot 0.4 e^{- 0.4 x} + 8 \cdot 0.6 e^{- 0.6 x}

Simplify

- 8 \cdot 0.4 e^{- 0.4 x} + 8 \cdot 0.6 e^{- 0.6 x} : - 3.2 e^{- 0.4 x} + 4.8 e^{- 0.6 x}

= - 3.2 e^{- 0.4 x} + 4.8 e^{- 0.6 x}

- 5 (10 x - 14 y = - 4)

\frac{( 2 n + 3 x ) ^{3}}{n ^{4}}

10 (z - 9 = - 40)

c^{2} d + 4 e f^{2} (c^{2} d - 4 e f^{2})

(- 0.4) (1 + 50 e^{- 0.4 x})^{2}
