Answer:
4.35x10¹⁷s is the age of the universe
Explanation:
The age of the universe is 13.8 billion years.
As we know, 1 billion years = 1x10⁹years
13.8 billion years * (1x10⁹years/ 1 billion years) = 13.8x10⁹ years.
As 1 year = 3.154x10⁷ seconds, 13.8x10⁹ years are:
13.8x10⁹ years * (3.154x10⁷ seconds / 1 year) =
4.35x10¹⁷s is the age of the universe
