(b)
Answer to Problem 35HP
The required expression is
Explanation of Solution
Given:
The expression is
Calculation:
Now, for second part consider the expression
Now, evaluate this expression by following the order of operations,
First solve brackets, then multiply or divide in order from left to right and after that addition or subtraction in order from left to right.
Now, since on going from left to right first operation is subtraction.
Subtract first and then add.
Thus the required expression with answer other than 17 is
Conclusion:
Therefore, the required expression with answer other than 17 is
