Answer 1

Place a decimal point between the first two digits (7 and 0) to get 7.004000

Now ask yourself: "how many places must I move the decimal to get it back to 7,004,000?"

Answer 2

Tell me what number you get

Answer 3

6

Answer 4

Do you mean standard index form? In which case it's 7.004 x10^6 (that's 7.004 times ten to the power of 6). Sometimes you might see it as 7.004E6; the 'E' means 'times 10 to the power of'.
Hope this helps!

Good, that 6 is the exponent over 10, which means

7,004,000 = 7.004 x 10^6
