Answer 3

Let's solve the expressions step by step:

1. 48 ÷ 8 + 7 * (72 ÷ 8) - 6 × 8

First, perform the operations inside the parentheses: 48 ÷ 8 = 6 72 ÷ 8 = 9

Now, we have: 6 + 7 * 9 - 6 × 8

Next, perform the multiplication and addition: 7 * 9 = 63 6 × 8 = 48

Now, we have: 6 + 63 - 48

Finally, perform the addition and subtraction: 6 + 63 = 69 69 - 48 = 21

So, the result of the first expression is 21.

2. 8 × 7 + (2 × 9) ÷ 3 - 81 ÷ (16 - 7)

First, perform the operations inside the parentheses: 2 × 9 = 18 16 - 7 = 9

Now, we have: 8 × 7 + 18 ÷ 3 - 81 ÷ 9

Next, perform the multiplication and division: 8 × 7 = 56 18 ÷ 3 = 6 81 ÷ 9 = 9

Now, we have: 56 + 6 - 9

Finally, perform the addition and subtraction: 56 + 6 = 62 62 - 9 = 53

So, the result of the second expression is 53.

To summarize:

1. 48:8+7*(72:8)-6×8 = 21
2. 8×7+(2×9):3-81:(16-7) = 53
