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

simplify

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

- e^{x}

Solution steps

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

Apply exponent rule:

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

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

= - e^{- x + 2 x}

Add similar elements:

- x + 2 x = x

= - e^{x}

\frac{- 48}{3}

(9.5 \times 1 0^{6}) \times (4 \times 1 0^{2})

- e^{- l n (3)}

(- 5)^{2}
