Answer:
b = 2x²
Step-by-step explanation:
Let the number of bacteria = x
Every hour, the number of bacteria doubles itself, = x * x = x²
But the bacteria started with 2g,
The number of bacteria present is equal to
2 * x² = 2x².
At every hour, the growth of the bacteria is at 2x²
30= 3x10= 3x2x5
300= 3x100=3x10x10=3x2^2x5^2
17=17x1=17
21=3x7
