Solution steps

4 (- 1.6) \cdot 1 0^{- 19}

Multiply the numbers:

4 (- 1.6) = - 6.4

= - 6.4 \cdot 1 0^{- 19}

= - 1 0^{- 19} \cdot 6.4

Apply exponent rule:

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

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

= - \frac{1}{1 0 ^{19}} \cdot 6.4

- \frac{1}{1 0 ^{19}} \cdot 6.4 = - \frac{6.4}{1 0 ^{19}}

= - \frac{6.4}{1 0 ^{19}}

\frac{6.4}{1 0 ^{19}} = \frac{64}{10 \cdot 1 0 ^{19}}

= - \frac{64}{10 \cdot 1 0 ^{19}}

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

= - \frac{64}{1 0 ^{20}}

Factor the number:

64 = 2^{6}

= - \frac{2 ^{6}}{1 0 ^{20}}

Factor

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

= - \frac{2 ^{6}}{2 ^{20} \cdot 5 ^{20}}

\frac{2 ^{6}}{2 ^{20}} = \frac{1}{2 ^{14}}

= - \frac{1}{2 ^{14} \cdot 5 ^{20}}

2^{14} = 16384

= - \frac{1}{5 ^{20} \cdot 16384}

3^{n} (2 \cdot 3^{n})
