I think you meant to write "scientific notation" instead of "specific notation"
To write 34000 in scientific notation, you must place the decimal point between the first two digits (3 and 4) to get 3.4
The question is now: "how many spots to the right must we move the decimal to go from 3.4 back to 34000.0?"
The answer to that question is "4 spots to the right"
That '4' is going to be the exponent over the 10 which is why
34000 = 3.4*10^4
The answer is choice D
