If 4+5-2=33 and 10+12-5=119 then 6+8-3=?

Question

If 2+3=3, 4+4=5, 4+5=7, 5+7=10, 5+8=12, 6+5=8
then (3+7)+2 = ?

Answer 1

73

---

The pattern is
a+b-c --> a^2+b^2-c^3

---

4+5-2=33 --> 4^2+5^2-2^3=33
10+ 12-5=119 --> 10^2+12^2-5^3=119
6 +8-3=? --> 6^2+8^2-3^3=73

Answer 2

its a^2+b^2-c^3 concept

means 4^2+5^2-2^3=>16+25-8=> 33
similarly 10^2+12^2-5^3=>100+144-125=>119
and hence 6^2+8^2-3^3=>36+64-27 =>73
