simplify (e^{-x})(1/(1+e^x))

simplify

(e^{- x}) (\frac{1}{1 + e ^{x}})

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

Solution steps

(e^{- x}) (\frac{1}{1 + e ^{x}})

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

= \frac{1}{e ^{x}} \cdot \frac{1}{e ^{x} + 1}

Multiply fractions:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

= \frac{1 \cdot 1}{e ^{x} ( 1 + e ^{x} )}

Multiply the numbers:

1 \cdot 1 = 1

= \frac{1}{e ^{x} ( e ^{x} + 1 )}

(2.5 \cdot 1 0^{- 6}) \cdot (5 \cdot 1 0^{- 4})

- 3 e^{- l n (3)}

5.63 \cdot 1 0^{- 4}

\frac{1}{4} e^{- \frac{4}{4}}

e^{- 2 (5)}
