simplify 2.1*10^{-8}

Solution

simplify

2.1 \cdot 1 0^{- 8}

Solution

0.000000021

Solution steps

2.1 \cdot 1 0^{- 8}

Apply exponent rule:

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

1 0^{- 8} = \frac{1}{1 0 ^{8}}

= 2.1 \cdot \frac{1}{1 0 ^{8}}

1 0^{8} = 100000000

= 2.1 \cdot \frac{1}{100000000}

2.1 \cdot \frac{1}{100000000} = \frac{2.1}{100000000}

= \frac{2.1}{100000000}

Divide the numbers:

\frac{2.1}{100000000} = 0.000000021

= 0.000000021
