Answer 2

Let's break down the given expression step by step:

72 : 9: This represents the division of 72 by 9. Therefore, 72 divided by 9 is equal to 8.

(4 × 2)64: Inside the parentheses, we have 4 multiplied by 2, which equals 8. So, the expression becomes 8 * 64.

8 * 64: Multiplying 8 by 64 results in 512.

8 + (-10): Adding 8 and -10 together gives us -2.

Now, let's put it all together:

72 : 9 : (4 × 2)64 : 8 + (-10)

8 : 8 * 64 : -2

Now, we'll simplify further:

8 : 8 is equal to 1.

1 * 64 is equal to 64.

Therefore, the final expression evaluates to:

1 : 64 : -2

The simplified expression is 1 : 64 : -2.
