square of first digit+square of second digit and reversing the digit we get answer

23 = 31
(2*2)+(3*3) = 13 and reversing the digit 31
similarly
34 = 52
(3*3)+(4*4) = 25 and reversing the digit 25

56 = 16
(5*5)+(6*6) = 61 and reversing the digit 16
so
78 = 311
(7*7)+(8*8) =113 and reversing the digit 311
