Example of Multiplication and Division using Scientific Notation
- $\dfrac {\paren {0 \cdotp 006} \paren {80 \, 000} } {0 \cdotp 04} = 12 \, 000$
Proof
\(\ds \dfrac {\paren {0 \cdotp 006} \paren {80 \, 000} } {0 \cdotp 04}\) | \(=\) | \(\ds \dfrac {\paren {6 \times 10^{-3} } \paren {8 \times 10^4} } {4 \times 10^{-2} }\) | Definition of Scientific Notation | |||||||||||
\(\ds \) | \(=\) | \(\ds \dfrac {6 \times 8 \times 10^{4 - 3} } {4 \times 10^{-2} }\) | Product of Powers | |||||||||||
\(\ds \) | \(=\) | \(\ds \dfrac {48} 4 \times 10^{1 - \paren {-2} }\) | Quotient of Powers | |||||||||||
\(\ds \) | \(=\) | \(\ds 12 \times 10^3\) | ||||||||||||
\(\ds \) | \(=\) | \(\ds 12 \, 000\) | Definition of Scientific Notation |
