simplify 10e^{-x}

Solution

simplify

10 e^{- x}

\frac{10}{e ^{x}}

Solution steps

10 e^{- x}

Apply exponent rule:

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

= 10 \cdot \frac{1}{e ^{x}}

Multiply fractions:

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

= \frac{1 \cdot 10}{e ^{x}}

Multiply the numbers:

1 \cdot 10 = 10

= \frac{10}{e ^{x}}

(2 - 5 x)^{- 2}

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

\frac{1}{2 π} e^{- \frac{1}{2} \cdot 0. 1^{2}}

(74)^{2}

0.5 \times 0.5 \times (\frac{1.96}{0.04})^{2}
