so close, but all your exponent are off by 1

should be 6x10^10 + 2x10^5 + 2x10^0

You can see it best by looking at your last term

your last part should be 2x10^0 or just plain + 2

(yours would have a value of 20 not 2)

e.g. 200,000 = 2 x 100,000 = 2x10^5

10 = 10^1

100 = 10^2

1000=10^3 ----> the exponent matches the number of zeros.
