In a Petri dish a certain type of bacterium doubles in number every 40 minutes, there were originally 64,or 2^6,bacteria in the dish after 20 minutes, the number of bacteria has doubled 3 times, multiplying by 2^3.Now the population of bacteria is 2^6•2^3. Expressed as a power, how many bacteria are in the Petri dish after 120

Step-by-step explanation:

Given

Increment = doubles every 40 minutes

Required

Determine the population after 120 minutes

First, we need to determine the fraction of 120 to 40

If for every 40 minutes, we have:

We'll have:

at the 120the minute

Apply law of indices

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
