Look for the number with the smallest number of significant figures, which in this case is 6.26 x 10^-14,Round to three significant figures in your answer and get 2.***When I say round to three sig figs, I mean for example,......
4.249 x 10^7 / (2.268 x 10^5 x 6.26 x 10^-14)

Do the math and solve first, and your answer will be 2.99274247 x 10^15

Look for the number with the smallest number of significant figures, which in this case is 6.26 x 10^-14, which has three significant figures

Round to three significant figures in your answer and get 2.99 x 10^15

***When I say round to three sig figs, I mean for example, if your answer was 2.997 x 10^15, your answer would round to 3.00 x 10^15 because the 7 would round the 9 up to a 10, which would round up the other 9, which would make your number 3. But since you need 3 sig figs, you'd make the number 3.00 x 10^15***
