simplify-0.2789100000000…sqrt(5)e^{-0.5*sqrt(5)}

simplify

- 0.2789100000000 \dots \cdot 5 \cdot e^{- 0.5 \cdot 5}

- 0.20388 \dots

Solution steps

- 0.27891 \dots 5 e^{- 0.5 5}

Apply exponent rule:

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

= - 5 \cdot 0.27891 \dots \cdot \frac{1}{e ^{5 \cdot 0.5}}

Multiply fractions:

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

= - 0.27891 \dots \cdot \frac{1 \cdot 5}{e ^{5 \cdot 0.5}}

\frac{1 \cdot 5}{e ^{0.5 5}} = 0.73101 \dots

= - 0.27891 \dots \cdot 0.73101 \dots

Multiply the numbers:

0.27891 \dots \cdot 0.73101 \dots = 0.20388 \dots

= - 0.20388 \dots

- x (x - 2)^{2} (2 x + 1)^{2}

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