expand 2.5x10^{-3}

Solution

expand

2.5 x 1 0^{- 3}

Solution

0.0025 x

Solution steps

2.5 x \cdot 1 0^{- 3}

Apply exponent rule:

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

= 2.5 \cdot \frac{1}{1 0 ^{3}} x

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= 2.5 \cdot \frac{1 \cdot x}{1 0 ^{3}}

Simplify

\frac{1 \cdot x}{1 0 ^{3}} : \frac{x}{1000}

= 2.5 \cdot \frac{x}{1000}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{x \cdot 2.5}{1000}

Divide the numbers:

\frac{2.5}{1000} = 0.0025

= 0.0025 x
