B 22.26 times 10^7
C 2.226 times 10^8
D 22.26 times 10^12

C 2.226 times 10^8

Step-by-step explanation:

5.3* 10^4    * 4.2 * 10^3

We multiply the numbers out front

5.3* 4.2 =22.26

We add the exponents

10^(4+3) = 10^7

22.26*10^7

But we are not done yet because The number out front has to be between 1 and less than 10

Move the decimal 1 place to the left and add 1 to the exponent

2.226 * 10 ^(7+1)

2.226*10^8

C
