3*6+5+6*8+3+8*10+7=36+5+48+3+80+7=41+51+87= 179
(235)9=2*81+3*9+5=162+27+5= 194
194-179=(15)10=(30)5
Ans=30
you are evaluate that expression in decimal, let (x)5 = (y)10 . ------ For avoiding confusion
3*6 +5+ 6*8 + 3 + 87 + x = 2*9*9 + 3*9 + 5 should be wrote as 3*6 +5+ 6*8 + 3 + 87 + y = 2*9*9 + 3*9 + 5 ===> y=33 then what is x? (x)5 = (33)10
3*6 +5+ 6*8 + 3 + 87 + x = 2*9*9 + 3*9 + 5
should be wrote as
3*6 +5+ 6*8 + 3 + 87 + y = 2*9*9 + 3*9 + 5 ===> y=33 then what is x?
(x)5 = (33)10
