1. AB+C^ * D E^ * F -
2. AB^ * C+D E^ * F/.
3. AB + C-D E^ * F/^ *
4. AB+C^ * D E^ * F/

Correct answer:

Option 4: AB+C^ * DE^ * F/

0 has highest precedence

*and / has same precedence while + and — has same precedence

(and/) and higher precedence than (+-)

Associativity is left to right.

(A+B) *C-D *E/F
AB+*C-D*E/F
AB+C*-D*E/F
AB+C*-DE/F
AB+C*-DE* F/
AB+C* DE* F/
