Can anbody show me its process​

Answer 1

Step-by-step explanation:

Given

$= \frac{1.5 \times {10}^{4} \times 4.5 \times {10}^{3} }{2.5 \times 10 ^{2} } \\ = \frac{6.75 \times {10}^{4 + 3} }{2.5 \times {10}^{2} } \\ = \frac{6.75 \times {10}^{7} }{2.5 \times {10}^{2} } \\ = 2.7 \times {10}^{7 - 2} \\ = 2.7 \times {10}^{5}$

Hope it will help :)
