There were originally 8, or 2^(three) bacteria in the dish. After 140 minutes, the number of bacteria has doubled 7 times, multiplying 2^(seven).Now the population of bacteria is 2^(three) x 2^(seven). Expressed as a power, how many bacteria are in the petri dish after 140 minutes

Respuesta :

Answer:

2^(10)

Explanation:

We will use the following property:

[tex]2^a\cdot2^b=2^{a+b}[/tex]

So, After 140 minutes the population was 2³ x 2⁷, then, using the property, we get that the expression equivalent is:

[tex]2^3\times2^7=2^{3+7}=2^{10}[/tex]

Therefore, the answer is 2^(10)
