Question

Please help!!!!!!!!!!!!

Answer 1

1.4*10 2nd power = 1400000000
8.25*10 2nd power = 825
1400000000*825= 1155000000000

Answer 2

Since 10 to the ninth power is 1000000000 and 1000000000 times 1.4 is 1400000000 and 10 to the second power is 100 and 100 times 8.25 is 825 you would subtract 1400000000 and 825 and get the answer of 1399999175.
