Question

A symbol operation is defined as follows:
  p ->^0 q means q
  p ->^1 q means p^q
  p ->^2 q means p^(p^q)
Then, the value of the expression ((4 ->^2 3); ((4 ->^2) ->^1 0)) =

A. -1
B. -0.5
C. 6
D. 7

Accepted Answer

7 A custom operation '->' is defined at three levels: level 0 just returns q, level 1 raises p to the power q, and level 2 raises p to p^q. We apply these rules step-by-step to evaluate the given composite expression. The key is substituting correctly at each nesting level.

A symbol operation is defined as follows: p ->^0 q means q p ->^1 q means p^q p ->^2 q means p^(p^q) Then, the value of the expression ((4 ->^2 3); ((4 ->^2) ->^1 0)) = A. -1 B. -0.5 C. 6 D. 7
