I don't know exactly what the question was, but I'm guessing it's the bacteria growth rate.

You can use the formula
final amount of bacteria = (initial amount of bacteria)(bacteria growth rate)^number of hours

So,
972 = (4)(x)^5

then simplify this equation to solve for x

x=3

the amount of bacteria increased 3 times more every hour for 5 hours
