Answer 2

Step-by-step explanation:

The age of the universe is 13.8 billion years.

We know that,

1 billion years = 10⁹ years

So,

`13.8\ \text{billion years}=13.8* 10^9\ \text{years}`

We need to convert the age of the universe to the scientific notation.

Since,
`1\ \text{year}=3.154* 10^7\ s`

So,

`13.8* 10^9\ \text{years}=13.8* 10^9* 3.154 * 10^7\\\\=4.35* 10^(17)\ s`

So, the age of the universe is
`4.35* 10^(17)\ s`.
