Decimal Notation

1.492 E - 20

Solution steps

3.73 \cdot 1 0^{- 21} \cdot 4

Multiply the numbers:

3.73 \cdot 4 = 14.92

= 14.92 \cdot 1 0^{- 21}

= 1 0^{- 21} \cdot 14.92

Apply exponent rule:

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

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

= \frac{1}{1 0 ^{21}} \cdot 14.92

\frac{1}{1 0 ^{21}} \cdot 14.92 = \frac{14.92}{1 0 ^{21}}

= \frac{14.92}{1 0 ^{21}}

\frac{14.92}{1 0 ^{21}} = \frac{1492}{100 \cdot 1 0 ^{21}}

= \frac{1492}{100 \cdot 1 0 ^{21}}

Factor the number:

1492 = 4 \cdot 373

= \frac{4 \cdot 373}{100 \cdot 1 0 ^{21}}

Factor the number:

100 = 4 \cdot 25

= \frac{4 \cdot 373}{4 \cdot 25 \cdot 1 0 ^{21}}

Cancel the common factor:

4

= \frac{373}{25 \cdot 1 0 ^{21}}
