Jason incorrectly simplified the expression (4.7*10^2)*(6.2*10^4). circle each step that shows an error. then correct each of those steps so that the expression is correctly simplified.

a step 1. 4.7*6.2*10^2*10^4
b step 2. (4.7*6.2)*(10^2*10^4)
c step 3. 29.14*10^8
d step 4. 2.914*10^6

Step C is incorrect: When you simplify exponents the rules are: for adding or subtracting, the base and the exponent must be equal; when multiplying the base must be the same, and the exponents will add; when dividing the base must be the same and the exponent will subtract.

Step D is incorrect: The last division is wrong, you could treat it with the general rule of exponents, subtracting the exponents of the base 10.

The correct procedure of each step is:

C.
