Well you see Bob, first you would use the commutative property and change it to some thing like this: (7.8* 800) *10 to the 12th= (7.8*80,000) *10 to the 10th.
(7.8*10 to the 12th power)*800
= 7.8*800* 10^12
= 62400 * 10^12
= 6.24 * 10^15
(7.8*10 to the 10th power)*80,000
= 624000 * 10^10
= 6.24 * 10^14
so what do you think ?
= 7.8*800* 10^12
= 62400 * 10^12
= 6.24 * 10^15
(7.8*10 to the 10th power)*80,000
= 624000 * 10^10
= 6.24 * 10^14
so what do you think ?
