Answer:

7.00\times 10^8-5.00\times 10^6 = 6.95\times 10^8

Explanation:

The given expression is :

7.00\times 10^8-5.00\times 10^6

We need to solve the above expression using operations and then express it in scientific notation.

First we will make the power of 10 same in both terms

7.00\times 10^8-(5.00\times 10^6\times \dfrac{100}{100})\\\\=7.00\times 10^8-(0.05\times 10^8)\\\\=(7-0.05)\times 10^8\\\\=6.95\times 10^8

Hence, the answer is 6.95\times 10^8.
