Need multiply. (7.1×10^4)⋅(4.8×10^3) which is the correct answer? a.)3.408×10^7 b.) 3.408×10^8 c.) 3.408×10^12 d.) 3.408×10^13

B

Step-by-step explanation:

No need to panic, it's much more simpler than you think.

10^4 = 10,000

10^3 = 1,000

(7.1 * 10,000) * (4.8 * 1,000) =

(7.1 * 4.8) * (10^3 * 10^4) =

= 34.08 * 10^7

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
