Solution steps

2.68 \cdot 1 0^{- 21}

Apply exponent rule:

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

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

= 2.68 \cdot \frac{1}{1 0 ^{21}}

2.68 \cdot \frac{1}{1 0 ^{21}} = \frac{2.68}{1 0 ^{21}}

= \frac{2.68}{1 0 ^{21}}

\frac{2.68}{1 0 ^{21}} = \frac{268}{100 \cdot 1 0 ^{21}}

= \frac{268}{100 \cdot 1 0 ^{21}}

Factor the number:

268 = 4 \cdot 67

= \frac{4 \cdot 67}{100 \cdot 1 0 ^{21}}

100 = 4 \cdot 25

= \frac{4 \cdot 67}{4 \cdot 25 \cdot 1 0 ^{21}}

Cancel the common factor:

4

= \frac{67}{25 \cdot 1 0 ^{21}}
