[?]×10

Answer 1

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 $6.95\times 10^8$.
