A. Complete expanded form of 4.728 in exponential notation?

Do you mean

4*10^0 + 7*10^-1 + 2*10^-2 + 8*10^-3?

If not, maybe you could splain just what you do want.

4+0.7+0.02+0.008

here the answer hope this helps if this is what your looking for!!

No wrong

4.728 complete expanded form of the decimal in exponential notation. Question is how do i solve this problem.

To express a decimal number in expanded form in exponential notation, you need to understand the concept of place value. The number 4.728 can be broken down into its individual place values:

The digit 4 is in the thousands place (10^3).
The digit 7 is in the hundreds place (10^2).
The digit 2 is in the tens place (10^1).
The digit 8 is in the ones place (10^0).
The digit 7 is in the tenths place (10^-1).
The digit 2 is in the hundredths place (10^-2).
The digit 8 is in the thousandths place (10^-3).

Now, to express this number in expanded form in exponential notation, we can write it as:

4.728 = 4 * (10^3) + 7 * (10^2) + 2 * (10^1) + 8 * (10^0) + 7 * (10^-1) + 2 * (10^-2) + 8 * (10^-3)

So, the complete expanded form of 4.728 in exponential notation is:

4.728 = 4 * (10^3) + 7 * (10^2) + 2 * (10^1) + 8 * (10^0) + 7 * (10^-1) + 2 * (10^-2) + 8 * (10^-3)
