simplify 2.1*10^{-10}

Solution

simplify

2.1 \cdot 1 0^{- 10}

Solution

\frac{21}{1 0 ^{11}}

+1

Decimal Notation

2.1 E - 10

Solution steps

2.1 \cdot 1 0^{- 10}

Apply exponent rule:

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

1 0^{- 10} = \frac{1}{1 0 ^{10}}

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

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

= \frac{2.1}{1 0 ^{10}}

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

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

10 \cdot 1 0^{10} = 1 0^{11}

= \frac{21}{1 0 ^{11}}
