ok, so you want this in scientific notation? how many significant figures?
multiply through by 8, now you have \[24 * 10^(14)\]
24 * 10^14
not done yet
for scientific notation you usually have only one leading digit, like 3 in the first case, here we have 24..

so 24 is actually 2.4 * 10
so 24 * 10^14 = 2.4 * 10 * 10^14
where 10^14 is actually 14 tens multiplied together...so we have 10 * 10 * 10 * 10 * .... 10 * 10...14 times
now 2.4 * 10 * 10^14 has 10 tens being multiplied
sorry 15 tens
