Question

Perform the following operation

and express the answer in
scientific notation.
7.00x 108 – 5.00x 106
[?]×10

Answer 1

`7.00* 10^8-5.00* 10^6` =
`6.95* 10^8`

Step-by-step explanation:

The given expression is :

`7.00* 10^8-5.00* 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* 10^8-(5.00* 10^6* (100)/(100))\\\\=7.00* 10^8-(0.05* 10^8)\\\\=(7-0.05)* 10^8\\\\=6.95* 10^8`

Hence, the answer is
`6.95* 10^8`.
