simplify-2e^{-0.4^2}0.4

simplify

- 2 e^{- 0. 4^{2}} 0.4

- 0.68171 \dots

Solution steps

- 2 e^{- 0. 4^{2}} \cdot 0.4

Apply exponent rule:

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

= - 2 \cdot 0.4 \cdot \frac{1}{e ^{0. 4^{2}}}

Multiply fractions:

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

= - 0.4 \cdot \frac{1 \cdot 2}{e ^{0. 4^{2}}}

\frac{1 \cdot 2}{e ^{0. 4^{2}}} = 1.70428 \dots

= - 0.4 \cdot 1.70428 \dots

Multiply the numbers:

0.4 \cdot 1.70428 \dots = 0.68171 \dots

= - 0.68171 \dots

(4 g^{6}) (10 g^{2})

(3 x^{2} y) (5 x y)

7.8 x 1 0^{- 2}

(4 \cdot 1 0^{6}) (3 \cdot 1 0^{6})
