Question

A bacteria culture begins with 8 bacteria which triple in size every week. How many bacteria exist in the culture after 4 weeks?

512
648
12,288
26,244

Answer 1

Here this is an exponential increase. So we can represent this problem through exponents. Because we have 8 as our starting number, we must include this in the required equation. Because the bacteria triple every week , and it tells us to determine hom many in four weeks we can represent it as 3⁴.

Answer 2

so our equation would be 8 * 3⁴ = x

Answer 3

sorry (8 * 3)⁴ = x

Answer 4

Nah Gdein you were correct earlier (: It was 8(3^4)

Answer 5

yeah I got to thinkin about it earlier, then I forgot to change it
