Evaluate \(\frac{0.0004 \times 80000}{4000 \times 0.002}\) [solved]

Question

Evaluate

\(\dfrac{0.0004 \times 80000}{4000 \times 0.002}\)

Answer 1

\( \begin{aligned} \frac{0.0004 \times 80000}{4000 \times 0.002} \\ \frac{4 \times 10^{-4} \times 8 \times 10^{4}}{4 \times 10^{3} \times 2 \times 10^{-3}} \\ \frac{4 \times 10^{4} \times 10^{-4}}{10^{3} \times 10^{-3}} \\ &=\frac{4 \times 10^{0}}{10^{0}} \\ &=\frac{4 \times 1}{1}=4 \end{aligned} \)
