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

simplify

(e^{- 2 x}) (2 e^{2 x})

2

Solution steps

(e^{- 2 x}) (2 e^{2 x})

Apply exponent rule:

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

e^{- 2 x} e^{2 x} = e^{- 2 x + 2 x}

= 2 e^{- 2 x + 2 x}

Add similar elements:

- 2 x + 2 x = 0

= 2 e^{0}

Apply rule

a^{0} = 1, a \neq = 0

e^{0} = 1

= 2 \cdot 1

Multiply the numbers:

2 \cdot 1 = 2

= 2

(- 5 y)^{3}

2 x^{- 0.5}

\frac{d ^{2}}{d ^{2} x} (e^{- x^{2}})

(6 x)^{2}
