Question

How do you simplify `(3times10^-4)+(3times10^7)`?

Answer 1

`(3×10^(−4))+(3×10^7)`

`=> (0.0003) + (30,000,000)`

We can see that, `(0.0003) < (30,000,000)`,
So when such a small number is added to such a huge one, we assume the smaller one to be 0.

`:. (3×10^(−4))+(3×10^7) = color(red)((3×10^7)`
