Answer 2

Answer with explanation:

A number is said to be in Scientific Notation , if it can be written in the form of

`A * 10^B`

Where A is any Real number and B can be any integer.

`1.\rightarrow 1.1 * 10^(213)-----\text{In scientific notation}\\\\2\rightarrow 7.8 * 10^(8)-----\text{In scientific notation}\\\\3.\rightarrow 3.02 * 10^(-10)-----\text{In scientific notation}\\\\4.\rightarrow 35 * 10^(4)-----\text{Not In scientific notation}`

`\rightarrow 35 * 10^4=3.5 * 10^5`
