Answer 3

Let's evaluate both expressions step by step:

Expression 1: (7×8+4)÷4+2

Step 1: Calculate 7×8 = 56 Step 2: Add 4 to the result of Step 1 = 56 + 4 = 60 Step 3: Divide the result of Step 2 by 4 = 60 ÷ 4 = 15 Step 4: Add 2 to the result of Step 3 = 15 + 2 = 17

So, the value of Expression 1 is indeed 17.

Expression 2: (7×8+4)÷(4+2)

Step 1: Calculate 7×8 = 56 Step 2: Add 4 to the result of Step 1 = 56 + 4 = 60 Step 3: Calculate 4+2 = 6 Step 4: Divide the result of Step 2 by the result of Step 3 = 60 ÷ 6 = 10

So, the value of Expression 2 is 10.

You are correct. The two expressions have different values. Expression 1 evaluates to 17, while Expression 2 evaluates to 10.
