simplify (e^{-kx})/(e^{kx)}

simplify

\frac{e ^{- k x}}{e ^{k x}}

e^{- 2 k x}

Solution steps

\frac{e ^{- k x}}{e ^{k x}}

Apply exponent rule:

\frac{x ^{a}}{x ^{b}} = x^{a - b}

= e^{- k x - k x}

Add similar elements:

- k x - k x = - 2 k x

= e^{- 2 k x}

e^{- 4.5} \cdot 4. 5^{4} \frac{1}{4 !}

sin (t) e^{- s t}

6.67 \cdot 1 0^{- 11} \frac{4 \cdot 2}{0. 4 ^{2}}

\frac{( x + 1 ) ^{2}}{( x + 2 ) ^{2}}
