simplify-42(-1.6)10^{-19}

simplify

- 42 \cdot (- 1.6) \cdot 1 0^{- 19}

\frac{21}{5 ^{20} \cdot 32768}

Decimal Notation

6.72 E - 18

Solution steps

- 42 (- 1.6) \cdot 1 0^{- 19}

Multiply the numbers:

42 (- 1.6) = - 67.2

= - (- 67.2) \cdot 1 0^{- 19}

Remove parentheses:

- (- 67.2) \cdot 1 0^{- 19} = 67.2 \cdot 1 0^{- 19}

= 67.2 \cdot 1 0^{- 19}

= 1 0^{- 19} \cdot 67.2

Apply exponent rule:

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

1 0^{- 19} = \frac{1}{1 0 ^{19}}

= \frac{1}{1 0 ^{19}} \cdot 67.2

\frac{1}{1 0 ^{19}} \cdot 67.2 = \frac{67.2}{1 0 ^{19}}

= \frac{67.2}{1 0 ^{19}}

\frac{67.2}{1 0 ^{19}} = \frac{672}{10 \cdot 1 0 ^{19}}

= \frac{672}{10 \cdot 1 0 ^{19}}

10 \cdot 1 0^{19} = 1 0^{20}

= \frac{672}{1 0 ^{20}}

Factor

672 : 2^{5} \cdot 21

= \frac{2 ^{5} \cdot 21}{1 0 ^{20}}

Factor

1 0^{20} : 2^{20} \cdot 5^{20}

= \frac{2 ^{5} \cdot 21}{2 ^{20} \cdot 5 ^{20}}

\frac{2 ^{5}}{2 ^{20}} = \frac{1}{2 ^{15}}

= \frac{21}{2 ^{15} \cdot 5 ^{20}}

2^{15} = 32768

= \frac{21}{5 ^{20} \cdot 32768}

e^{- \frac{1}{1.5} X^{30}}

(3 x^{3}) (12 x^{2} y^{2} z^{3})

\frac{e ^{3 x^{2}}}{e ^{12}}

(4 - 9 \cdot 8)^{3}

- 4 x \cdot e^{- \frac{x}{4}}
