simplify 1.610^{-19}4.5

simplify

1.6 \cdot 1 0^{- 19} \cdot 4.5

\frac{9}{5 ^{20} \cdot 131072}

Decimal Notation

7.2 E - 19

Solution steps

1.6 \cdot 1 0^{- 19} \cdot 4.5

Multiply the numbers:

1.6 \cdot 4.5 = 7.2

= 7.2 \cdot 1 0^{- 19}

= 1 0^{- 19} \cdot 7.2

Apply exponent rule:

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

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

= \frac{1}{1 0 ^{19}} \cdot 7.2

\frac{1}{1 0 ^{19}} \cdot 7.2 = \frac{7.2}{1 0 ^{19}}

= \frac{7.2}{1 0 ^{19}}

\frac{7.2}{1 0 ^{19}} = \frac{72}{10 \cdot 1 0 ^{19}}

= \frac{72}{10 \cdot 1 0 ^{19}}

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

= \frac{72}{1 0 ^{20}}

Factor

72 : 2^{3} \cdot 9

= \frac{2 ^{3} \cdot 9}{1 0 ^{20}}

Factor

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

= \frac{2 ^{3} \cdot 9}{2 ^{20} \cdot 5 ^{20}}

\frac{2 ^{3}}{2 ^{20}} = \frac{1}{2 ^{17}}

= \frac{9}{2 ^{17} \cdot 5 ^{20}}

2^{17} = 131072

= \frac{9}{5 ^{20} \cdot 131072}

(5.2 \cdot 1 0^{- 6}) \cdot 0.42

70 e^{- 0.4 (3)}

e^{2} e^{- x}

\frac{d}{d x} (m (x - h (m, x)))

e^{(- 1439. 1^{- 2} λ T)}
