You can put this solution on YOUR website!

b. Multiplication distributes over subtraction.
x%28a-b%29+=+xa+-+xb, for example:
3%285-2%29+=+3%2A5+-+3%2A2+=+15+-+6+=+9
3%285-2%29+=+3%2A3+=+9

c. Exponents distribute over multiplication.
%28a%2Ab%29%5Ex+=+a%5Ex%2Ab%5Ex%29
%282%2A3%29%5E2+=+6%5E2+=+36
2%5E2+%2A+3%5E2+=+4+%2A+9+=+36

d. Multiplication distributes over addition.
x%28a%2Bb%29+=+xa+%2B+xb
3%285%2B2%29+=+3%2A5+%2B+3%2A2+=+15+%2B+6+=+21
3%285%2B2%29+=+3%2A7+=+21
The answer is, therefore, letter a:
a. Exponents distrubute over addition
