Answer
Answer
AIConversion from infix to prefix:
Given infix: P / Q + (S * F + X / R)
1. Parenthesized term: (S * F + X / R)
- S * F = * S F
- X / R = / X R
- * S F + / X R = + * S F / X R
2. Division: P / Q = / P Q
3. Addition: (/ P Q) + (+ * S F / X R) = + / P Q + * S F / X R
Prefix form: + / P Q + * S F / X R
