Solution steps

2 (2.31 \cdot 1 0^{- 19} (\frac{1 \cdot ( - 1 )}{0.8}))

Apply rule:

(a) = a

(\frac{1 \cdot ( - 1 )}{0.8}) = \frac{1 \cdot ( - 1 )}{0.8}

= 2 \cdot 2.31 \cdot 1 0^{- 19} \cdot \frac{1 \cdot ( - 1 )}{0.8}

Apply exponent rule:

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

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

= 2 \cdot 2.31 \cdot \frac{1}{1 0 ^{19}} \cdot \frac{1 \cdot ( - 1 )}{0.8}

2.31 \cdot \frac{1}{1 0 ^{19}} \cdot \frac{1 \cdot ( - 1 )}{0.8} = \frac{- 2.31}{1 0 ^{19} \cdot 0.8}

= 2 \cdot \frac{- 2.31}{1 0 ^{19} \cdot 0.8}

\frac{- 2.31}{1 0 ^{19} \cdot 0.8} = \frac{231}{80 \cdot 1 0 ^{19}}

= 2 \cdot \frac{231}{80 \cdot 1 0 ^{19}}

2 \cdot \frac{231}{80 \cdot 1 0 ^{19}} = \frac{231}{40 \cdot 1 0 ^{19}}

= \frac{231}{40 \cdot 1 0 ^{19}}
