Answer 5

for scientific notation you usually have only one leading digit, like 3 in the first case, here we have 24..

Answer 6

so 24 is actually 2.4 * 10

Answer 7

so 24 * 10^14 = 2.4 * 10 * 10^14

Answer 8

where 10^14 is actually 14 tens multiplied together...so we have 10 * 10 * 10 * 10 * .... 10 * 10...14 times

Answer 9

now 2.4 * 10 * 10^14 has 10 tens being multiplied
