divide by 2.5×10 (2)
its answer is 2.7 ×10 (5)
Can anbody show me its process​

Answer 1

Explanation:

Given

`= \frac{1.5 * {10}^(4) * 4.5 * {10}^(3) }{2.5 * 10 ^(2) } \\ = \frac{6.75 * {10}^(4 + 3) }{2.5 * {10}^(2) } \\ = \frac{6.75 * {10}^(7) }{2.5 * {10}^(2) } \\ = 2.7 * {10}^(7 - 2) \\ = 2.7 * {10}^(5)`

Hope it will help :)
