Multiply all the numbers and tell me the answer

This is a rate problem. You have a rate: $$3.9*10^{33} \text{ ergs/s}$$ and you want to know the total produced if that rate is applied for a certain amount of time: $x = r t$where $$x$$ is the amount produced, $$r$$ is the rate and $$t$$ is the time $r = 3.9*10^{33}\text{ ergs/s}$$t=2.45*10^5\text{ s}$$x = r t = (3.9*10^{33}\text{ ergs/s})(2.45*10^5\text{ s})$$=(3.9*10^{33}\text{ ergs/}\cancel{\text{s}})(2.45*10^5\cancel{\text{ s}})$$=(3.9*10^{33})(2.45*10^5)\text{ ergs}$ Can you do that multiplication?
