The answer would be positive so ignore the negatives.
E because its not on there
2 and 3/4=2+3/4
1 and 1/3=1+1/3
2 and 3/4 minus (1 and 1/3)
2+3/4-(1+1/3)
2+3/4-1-1/3
2-1+3/4-1/3
1+3/4-1/3
make bottom number same
3/4-1/3
3/4 times 3/3=9/12
1/3 times 4/4=4/12
3/4-1/2=9/12-4/12=5/12
1+5/12
1 and 5/12
Start by looking at simplifying the smaller problems
anything to the power zero is 1

next apply the power of a power rule... multiply the powers

which becomes
