while inputting this into a high power calculator is certainly an option, one way you can determine the answer is to predict patterns and narrow down the selection of answers.
first, notice that there are 0s ending every number, this solidifies that thew following answer must be terminated with a zero at the one's digit, this rules out B and C.
Now, all we have left with are 8 digit A and 10 digit D
here, if we substitute all numbers over 1 into a 1, we get the following statement 1000+1000+10000/10 which comes out to 1000000000 (1000 10000 is the same as 10^3 10^4) / 10 and it ultimately equals 10^8, far below answer D but perfect for answer A
