simplify 2.1(10^{-9})

Solution

simplify

2.1 (1 0^{- 9})

Solution

0.0000000021

Solution steps

2.1 (1 0^{- 9})

Apply rule:

(a) = a

(1 0^{- 9}) = 1 0^{- 9}

= 2.1 \cdot 1 0^{- 9}

Apply exponent rule:

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

1 0^{- 9} = \frac{1}{1 0 ^{9}}

= 2.1 \cdot \frac{1}{1 0 ^{9}}

1 0^{9} = 1000000000

= 2.1 \cdot \frac{1}{1000000000}

2.1 \cdot \frac{1}{1000000000} = \frac{2.1}{1000000000}

= \frac{2.1}{1000000000}

Divide the numbers:

\frac{2.1}{1000000000} = 0.0000000021

= 0.0000000021
