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.
