Add them up:
5 + 300 + 8 = 513
I suspect that you may have a zero missing:
either: 50 + 300 + 8 = 358
or: 5 + 300 + 80 = 385
Expanded form is usually written with the biggest number first and the rest in decreasing value, ie
358 = 300 + 50 + 8
385 = 300 + 80 + 5
That depends what you mean by "standard form". That is the standard form for an addition. On the other hand, you can actually carry out the addition, and write the result as a single number.
The total, in standard form, is 3.13*10^2

Expanded form (50,000+300+70+2) need answer in standard form
The sum is 90,005,000,300 (ninety billion, five million, three hundred).
324 is the standard form.
