2) 9.82x10^5
= 98,200,000.
3) 9x10^3
= 0.0009
4) 7.24x10^6

#1 is correct.
The power of 10 refers to the number of positions the decimal point has to be moved, not the number of zeroes.
So for #2, it should be
9.82000*100000=982000
Similarly, for #3,
9x10^3=9/1000=0.009
I will leave #4 for you to try.
