Question

Scientific Notation:
what’s (2.2 x 10 to the -4) - (3 x 10 to the 2)

Answer 1

`2.23*10^4`

Explanation:

In order to get the answer to this question you need to turn the scientific notations into standard form then subtract the two standard forms.

`(2.2*10^(-4))-(3*10^2)`

Turn the notations into standard form:

`2.2*10^(-4) = .00022`

`3*10^2=300`

`.00022-300=22300`

`=22300`

Turn into notation form:

`22300 = 2.23*10^(4)`

Hope this helps.
