Question

The population of a bacteria grows 10,000 times in 10 hours. if the initial number of bacteria is 30, find the population of bacteria after 20 hours.​

Answer 1

Answer:

30 × 10,000² = 3 × 10⁹ bacteria

Step-by-step explanation:

Given :

The population of a bacteria grows 10,000 times in 10 hours.

If the initial number of bacteria is 30, find the population of bacteria after 20 hours.​

Solution :

We know that,

The population of bacteria grows 10,000 times in 10 hours,.

In first 10 hours, it increases by 10,000

⇒ 30 × 10,000 = 3 × 10⁵ bacteria

In next 10 hours,

It replicates again by 10,000

⇒ ( 30 × 10,000) x 10,000 = 3 × 10⁵ × 10,000 = 3 × 10⁹ bacteria
