It's likely that C was going to be the answer since A and B were incorrect. We don't know if there was going to be a D. Here's the correct answer: 5000000000 + 900000000 + 80000000 + 2000000 + 700000 + 50000 + 7
360,420 is the standard form of 300000 plus 60000 plus 400 plus 20.
If you know the expanded form (800000 + 4000 + 60 + 2), you can put the added numbers together to find the total, in standard form. Think of the pieces as numerical nesting dolls: if you line them up along the right, each number sets into the place beneath it, one layer at a time. This is how they can be lined up (ignore the dashes on the sides):--------2------60---4000800000Now, watch as each smallest piece falls into its place in the next number, until they are all nested into one number:--------2------60---4000800000------62---4000800000---4062800000804062There's the answer in standard form: 804,062.

To write the expression 900,000 plus 80,000 plus 500 plus 7 in standard form, first, add the numbers together: 900,000 + 80,000 + 500 + 7 equals 980,507. In standard form, this can be expressed as (9.80507 \times 10^5).
4000 + 10 + 3 + 0.02 = 4013.02 4000 ___10 ____3 ____0.02 ---------- 4013.02 =======
900000 + 900000 = 1800000
