simplify 2.1*10^{-5}

Solution

simplify

2.1 \cdot 1 0^{- 5}

Solution

0.000021

Solution steps

2.1 \cdot 1 0^{- 5}

Apply exponent rule:

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

1 0^{- 5} = \frac{1}{1 0 ^{5}}

= 2.1 \cdot \frac{1}{1 0 ^{5}}

1 0^{5} = 100000

= 2.1 \cdot \frac{1}{100000}

2.1 \cdot \frac{1}{100000} = \frac{2.1}{100000}

= \frac{2.1}{100000}

Divide the numbers:

\frac{2.1}{100000} = 0.000021

= 0.000021
