Question

How do you solve `1.12\times 10^ { 2} + 1.017\times 10^ { 3}`?

Answer 1

See the entire solution process below:

Explanation:

To add these two scientific notation expressions the 10s terms must be to the same power. Therefore, we can convert the second expression:

`1.017 xx 10^ = 10.17 xx 10^2`

We can now rewrite the expression in the problem as:

`1.12 xx 10^2 + 10.17 xx 10^2 = (1.12 + 10.17)10^2`

We can now add the terms:

`11.29 xx 10^2` or `1.129 xx 10^3`
