simplify

(- 3) e^{- 2}

- \frac{3}{e ^{2}}

Decimal Notation

- 0.40600 \dots

Solution steps

(- 3) e^{- 2}

Apply exponent rule:

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

= (- 3) \frac{1}{e ^{2}}

Remove parentheses:

(- a) = - a

= - 3 \cdot \frac{1}{e ^{2}}

Multiply fractions:

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

= - \frac{1 \cdot 3}{e ^{2}}

Multiply the numbers:

1 \cdot 3 = 3

= - \frac{3}{e ^{2}}

850000 (1 + 0.04)^{- 6}

a b \times b a

\frac{e ^{130}}{e ^{70}}

- x^{2} y^{2} (5 x^{2} - 8 x y + y^{2})
