simplify e^{-9}*9

Solution

simplify

e^{- 9} \cdot 9

\frac{9}{e ^{9}}

Decimal Notation

0.00111 \dots

Solution steps

e^{- 9} \cdot 9

Apply exponent rule:

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

= 9 \cdot \frac{1}{e ^{9}}

Multiply fractions:

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

= \frac{1 \cdot 9}{e ^{9}}

Multiply the numbers:

1 \cdot 9 = 9

= \frac{9}{e ^{9}}

(4 x^{2} y) (2 x y^{2})

ln (1 - x^{2}) \cdot ln (1 - x^{2})

e^{2 x} (\frac{1}{2} e^{2 x})

((\frac{1}{4})^{'})^{- 2}

0.2 \cdot 1 0^{- 3} \cdot \frac{38 \cdot 3.5}{183.4 \cdot 10}
