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

simplify

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

- e^{- 2 x}

Solution steps

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

Apply exponent rule:

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

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

= - e^{- x - x}

Add similar elements:

- x - x = - 2 x

= - e^{- 2 x}

3.6 \cdot 1 0^{- 2}

(6.626 \cdot 1 0^{- 34}) (2.998 \cdot 1 0^{8})

100 e^{- 0.087 (9)}

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

(10 + 7) (10 + 7)
