Question
Express $\frac{1.5 \times 10^6}{2.5 \times 10^4}$ in the standard form.
✓
Answer
We have, $\frac{1.5 \times 10^6}{2.5 \times 10^4}$
$
\begin{array}{l}
=\frac{1.5 \times 10^2 \times 10^4}{2.5 \times 10^4}=\frac{150}{2.5} \times 10^{4-4} \\
=\frac{150}{2.5} \times 10^0=60 \times 1=60 \\
=6.0 \times 10^1=6.0 \times 10
\end{array}
