Question

5+3=28
9+1=810
8+6=214
5+4=19
then 7+3=

Answer 1

the correct answer is -
7 + 3 = 410

================================

reason -

1)5-3 = 2/ 5+3 = 8
28

2) 9-1 = 8/9+1 = 10
810

3)8-6=2/8+6=14
214

4)5-4=1/5+4=9
19

so
7-3=4/7+3=10
410

Answer 2

5+3 = (5-3)(5+3) = 28
9+1 = (9-3)(9+3) = 810
8+6 = (8-3)(8+3) = 214
5+4 = (5-3)(5+3) = 19
similarly
7+3 = (7-3)(7+3) = 410
