What is the sum of the first three digits multiplied by the last digit of the number 7549? Express your answer as an equation.

Let A represent the first three digits and B represent the last digit. A = 754, B = 9. The sum of A and B can be expressed as A + B = 754 + 9 = 763.

What is the sum of the digits in the number 7549 minus the product of its digits, divided by the sum of the two smallest digits squared, multiplied by the largest digit plus one?

The sum of the digits (7+5+4+9) is 25. The product of the digits (7x5x4x9) is 1260. The sum of the two smallest digits (4+5) is 9. Squaring 9 gives 81. The largest digit is 9. So, the expression becomes (25 - 1260) / (81) x (9+1) = (-1235/81) x 10 = -151.98. Rounded to the nearest whole number, the answer is -152.

What is the sum of the prime factors of 7549?

Prime factorization of 7549 = 71 * 107 So, the sum of the prime factors of 7549 is 71 + 107 = 178.
