\begin{gathered} \frac{1.5 \times {10}^{6} }{2.5 \times {10}^{ - 4} } \\ \\ = \frac{1.5}{2.5} \times \frac{ {10}^{6} }{ {10}^{ - 4} } \\ \\ = \frac{1.5}{2.5} \times {10}^{6 - ( - 4)} \\ \\ = \frac{15}{25} \times {10}^{10} \\ \\ = 0.6 \times {10}^{10} \\ \\ = 6.0 \times {10}^{ - 1} \times {10}^{10} \\ \\ = 6.0 \times {10}^{9} \end{gathered}2.5×10−41.5×106=2.51.5×10−4106=2.51.5×106−(−4)=2515×1010=0.6×1010=6.0×10−1×1010=6.0×109
