What is the cube root of the sum of the digits of 7828 multiplied by the square of the tens digit minus the units digit, divided by the ones digit plus the hundreds digit minus the thousands digit, multiplied by 10?

The sum of the digits of 7828 is 7 + 8 + 2 + 8 = 25. The tens digit is 8 and the units digit is 8. So, (25^1/3) * (8^2 - 8) / (8 + 2 - 7) * 10 = 5 * 56 / 3 * 10 = 1866.66666667.

Question: What is the sum of the digits in the number 7828?

To find the sum of the digits in the number 7828, we add the individual digits: 7 + 8 + 2 + 8 = 25.

Math question: If the number 7828 is increased by 25% and then decreased by 15%, what is the resulting number?

To find the answer, first calculate the increase: 7828 + (25/100) * 7828 = 9785. Next, determine the decrease: 9785 - (15/100) * 9785 = 8317.25. Thus, the resulting number is 8317.25 after increasing 7828 by 25% and then decreasing it by 15%.
