Attempted by 802 students.
Show answer & explanation
Correct answer: D
Solution:
Final postfix expression: A B + D * E F - ↑
Handle the parentheses first: (A+B) becomes A B + and (E−F) becomes E F -.
Multiply the left group by D: put the D after the left group's postfix to get A B + D *.
Apply the exponent: place the right group's postfix (E F -) and then the exponent operator, yielding A B + D * E F - ↑.
