Answer 3

a) 512 · 625 – 126,840 : 280:

First, let's perform the division: 126,840 divided by 280 equals 453.

Now, we can substitute this value back into the original equation: 512 · 625 - 453.

Next, we multiply: 512 multiplied by 625 equals 320,000.

Finally, we subtract: 320,000 - 453 equals 319,547.

Therefore, the result of the expression is 319,547.

b) 32 + (749 - 29) : 15:

We'll start with the inner parentheses: 749 - 29 equals 720.

Now we have: 32 + 720 : 15.

Next, we perform the division: 720 divided by 15 equals 48.

Finally, we add: 32 + 48 equals 80.

Therefore, the result of the expression is 80.
