Answer 3

Let's solve the mathematical expressions step by step:

a) 521 * 706: The product of 521 and 706 is 367,726.

b) 61600 : 40: Dividing 61,600 by 40 gives us the result of 1,540.

c) 15428 : 38: Dividing 15,428 by 38 gives us the result of 406.

d) 249 + 5160 : (256 - 4 * 61): First, let's evaluate the expression inside the parentheses: 4 * 61 equals 244. Subtracting 244 from 256 gives us 12.

Next, we divide 5,160 by 12: 5160 : 12 equals 430.

Finally, we add 249 to 430: 249 + 430 equals 679.

Therefore, the result of the expression 249 + 5160 : (256 - 4 * 61) is 679.
