I can do it in 90. I'm not at all familiar with the 15C, however, so I may have made a mistake.
The idea is to do as much as possible in the setup.
So,
A: calculates and shows the 2 numbers,
R/S: doubles REG 1 & A
B: halves REG 2 & A

setup: total 41
Code:
 (2)  g P/R  (2)  f Clear PGM  (4)    2 STOx 1  (2)    GTO A  (3)  f LBL B  (4)    2 STO/ 2  (3)  f LBL A  (2)    RCL 1  (1)    ENTER  (2)  f X^2  (1)    +  (2)    RCL 2  (2)  g LN  (1)    -  (2)  f PSE  (2)  g LSTX  (1)    ENTER  (1)    +  (2) g P/R  (2) f USER

calc: total 49 (last two entries are calculated in reverse order)
Code:
(13)  3.12 STO 1 2.56 STO 2 A ( 1)  B ( 1)  B ( 1)  R/S ( 1)  R/S ( 2)  R/S B ( 1)  B ( 7)  1.32 STO 2 A ( 8)  18.59 STO 1 A ( 8)  17.63 STO 1 A ( 5)  4 STOx 2 A ( 1)  B
Total: 90
