simplify (4.9+7.4)910^{-6}

simplify

(4.9 + 7.4) \cdot 9 \cdot 1 0^{- 6}

0.0001107

Solution steps

(4.9 + 7.4) \cdot 9 \cdot 1 0^{- 6}

4.9 + 7.4 = 12.3

= 12.3 \cdot 9 \cdot 1 0^{- 6}

Apply exponent rule:

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

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

= 12.3 \cdot 9 \cdot \frac{1}{1 0 ^{6}}

1 0^{6} = 1000000

= 12.3 \cdot 9 \cdot \frac{1}{1000000}

Multiply the numbers:

12.3 \cdot 9 = 110.7

= 110.7 \cdot \frac{1}{1000000}

= \frac{1}{1000000} \cdot 110.7

\frac{1}{1000000} \cdot 110.7 = \frac{110.7}{1000000}

= \frac{110.7}{1000000}

Divide the numbers:

\frac{110.7}{1000000} = 0.0001107

= 0.0001107
