SOLUTION: I am doing exponents in expanded form and have a question: In the number 1,203,487,386 when I start to expand this to (1 x 10-10)+(2 x 10-9)+ do I include the 0 or leave it out?)

You can put this solution on YOUR website!
You should include the zero for completeness, and notice that you start at an exponent of 9:
1,203,487,386 =
1,000,000,000 = 1X10%5E9
200,000,000 = 2X10%5E8
-------------------------
3,000,000 = 3X10%5E6
400,000 = 4X10%5E5
80,000 = 8X10%5E4
7,000 = 7X10%5E3
300 = 3X10%5E2
80 = 8X10%5E1
6 = 6X10%5E0 Recall that 10%5E0+=+1
