simplify 4210^{-6}2.5

Solution

simplify

42 \cdot 1 0^{- 6} \cdot 2.5

Solution

\frac{21}{200000}

+1

Solution steps

42 \cdot 1 0^{- 6} \cdot 2.5

Multiply the numbers:

42 \cdot 2.5 = 105

= 105 \cdot 1 0^{- 6}

= 1 0^{- 6} \cdot 105

Apply exponent rule:

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

1 0^{- 6} = \frac{1}{1 0 ^{6}}

= \frac{1}{1 0 ^{6}} \cdot 105

1 0^{6} = 1000000

= \frac{1}{1000000} \cdot 105

\frac{1}{1000000} \cdot 105 = \frac{21}{200000}

= \frac{21}{200000}
