Answer 1

Решение:

23 * (6 - 5) = 23 * 1 = 23

23 * (6 - 5) = 23 * 6 - 23 * 5 = 138 - 115 = 23

23 * (6 - 5) = (20 + 3) * (6 - 5) = (20 + 3) * 1 = 20 + 3 = 23

$\tt\displaystyle 64:(2*8)=64:16=4\\\\64:(2*8)=(64:2):(64:8)=32:8=4\\\\64:(2*8)=(8 * 8):(2*8)=\frac{8*8}{2*8}=\frac{8}{2}=4$

Answer 2

To find the value of each expression, let's simplify them step by step:

1. 23 . (6 - 5)

Step 1: Perform the operation inside the parentheses. 6 - 5 = 1

Step 2: Multiply 23 by the result of the operation inside the parentheses. 23 * 1 = 23

So, the value of 23 . (6 - 5) is 23.

2. 23 . (6 - 5) = 23 . (6 - 5)

The expression is the same as the previous one, so the value is also 23.

3. 23 . (6 - 5) = 23 . (6 - 5) = 23 . (6 - 5)

This expression is also identical to the previous ones, and its value is 23.

4. 64 : (2 . 8)

Step 1: Perform the operation inside the parentheses. 2 . 8 = 16

Step 2: Divide 64 by the result of the operation inside the parentheses. 64 : 16 = 4

So, the value of 64 : (2 . 8) is 4.

5. 64 : (2 . 8) = 64 : (2 . 8)

The expression is the same as the previous one, so the value is also 4.

6. 64 : (2 . 8) = 64 : (2 . 8) = 64 : (2 . 8)

This expression is also identical to the previous ones, and its value is 4.

In summary:

1. 23 . (6 - 5) = 23
2. 23 . (6 - 5) = 23
3. 23 . (6 - 5) = 23
4. 64 : (2 . 8) = 4
5. 64 : (2 . 8) = 4
6. 64 : (2 . 8) = 4
