Answer 2

To evaluate the expression 1:(2-3:(4-5:(6-x))), let's break it down step by step:

1. First, let's evaluate the expression 6-x: Since we don't have any specific value for x, we can't simplify it further. So we keep it as 6-x.

2. Next, let's evaluate the expression 4-5:(6-x): Following the order of operations, we need to evaluate the expression inside the parentheses first. Since 6-x cannot be simplified further, we keep it as 6-x. Therefore, 4-5:(6-x) becomes 4-5*(6-x).

3. Now, let's evaluate the expression 2-3:(4-5:(6-x)): Similar to the previous step, we need to evaluate the expression inside the parentheses first. 4-5*(6-x) cannot be simplified any further, so we keep it as 4-5*(6-x). Therefore, 2-3:(4-5:(6-x)) becomes 2-3*(4-5*(6-x)).

4. Finally, let's evaluate the expression 1:(2-3:(4-5:(6-x))): Again, we need to evaluate the expression inside the parentheses first. 2-3*(4-5*(6-x)) cannot be simplified any further, so we keep it as 2-3*(4-5*(6-x)). Therefore, 1:(2-3:(4-5:(6-x))) becomes 1*(2-3*(4-5*(6-x))).

Since there are no further operations or simplifications to perform, we have the final expression: 1*(2-3*(4-5*(6-x))).

Without any specific value for x, we cannot calculate the exact result of this expression. Therefore, none of the given options (A, B, C, D, E) can be determined without additional information.
