Final answer:
To find 1#((2#3)#4), solve the expression step by step using the defined operation A#B as 2A - B. The final result of the expression 1#((2#3)#4) is 4.
Step-by-step explanation:
The student is asking to solve an expression using a given operation defined by A#B which means 2A - B. The specific expression to solve is 1#((2#3)#4). Let's solve it step by step.
- First, we solve the innermost expression: 2#3 which equals 2*2 - 3 = 4 - 3 = 1.
- Next, we take the result from step 1 and use it in the next part of the expression: (1#4) which translates to 2*1 - 4 = 2 - 4 = -2.
- Finally, we take the result from step 2 and complete the entire expression: 1#(-2) which equals 2*1 - (-2) = 2 + 2 = 4.
Thus, the calculated value of 1#((2#3)#4) is 4.
