Solution steps

0.7 (3 \cdot 1 0^{- 19})

Apply exponent rule:

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

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

= 0.7 \cdot 3 \cdot \frac{1}{1 0 ^{19}}

3 \cdot \frac{1}{1 0 ^{19}} = \frac{3}{1 0 ^{19}}

= 0.7 \cdot \frac{3}{1 0 ^{19}}

0.7 \cdot \frac{3}{1 0 ^{19}} = \frac{2.1}{1 0 ^{19}}

= \frac{2.1}{1 0 ^{19}}

\frac{2.1}{1 0 ^{19}} = \frac{21}{10 \cdot 1 0 ^{19}}

= \frac{21}{10 \cdot 1 0 ^{19}}

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

= \frac{21}{1 0 ^{20}}

2 e^{- 0.288 t}

(6.67 \cdot 1 0^{- 11}) (0.545) (0.108)

1500 \cdot e^{- 2000 \cdot (\frac{1}{240} - \frac{1}{289})}

e^{- 3.2} \cdot 3. 2^{2}
