Answer 1

There you go

Explanation:

Answer 2

Answer with explanation:

W have to find the value of :

`[A=1.93 * 10^7] - [B=9.7 * 10^6]`

Here exponent of 10 differs in both of these terms. So, to find the difference of A and B, we should make exponent of 10 equal in both the terms.

Exponent of A is Higher,so we will try to make this equal to exponent of 10 in B.

`A=1.93 * 10^7\\\\A=19.3 * 10^6\\\\A-B=19.3 * 10^6-9.7 * 10^6\\\\=(19.3-9.7) * 10^6\\\\=9.6* 10^6`
