Question

Bacteria can divide in every 20 minutes.So, one bacterium can multiply to 2 in 20 minutes .4 in 40 minutes ,and so on .How many bacteria will there be in 6 hours ?Write your answer using exponents and then evaluate .

Answer 1

in 6 hours
6 hours in minute =6
$6 \times 60 = 360$
in 360 minutes 36 bacteria are divided

Answer 2

6 hours = 360 minutes

Since bacteria at the rate of 10min/bacteria...

Therefore bacteria in 360 minutes =

360/10=36

Multiply by two.. that means bacteria be x (assuming)

2x = 36

x = 18

Exponent = 2 to the power 18

Exponential value = 2,62,144

Hope it helped
