The result of evaluating the postfix expression 10 5 + 60 6 / * 8 - is:

To evaluate the postfix expression 10 5 + 60 6 / * 8 -, we use a stack-based approach: Step 1: Push 10 onto the stack. Stack: [10] Step 2: Push 5 onto the stack. Stack: [10, 5] Step 3: Encounter '+', pop 5 and 10, compute 10 + 5 = 15, push 15. Stack: [15] Step 4: Push 60 onto the stack. Stack: [15, 60] Step 5: Push 6 onto the stack. Stack: [15, 60, 6] Step 6: Encounter '/', pop 6 and 60, compute 60 / 6 = 10, push 10. Stack: [15, 10] Step 7: Encounter '*', pop 10 and 15, compute 15 * 10 = 150, push 150. Stack: [150] Step 8: Push 8 onto the stack. Stack: [150, 8] Step 9: Encounter '-', pop 8 and 150, compute 150 - 8 = 142, push 142. Stack: [142] Final result: 142.
