Math question: What is the sum of the digits in the number 2515?

To find the sum of the digits in 2515, we need to add up each individual digit. The digit in the thousands place is 2, in the hundreds place it is 5, in the tens place it is also 1, and in the units place, it is 5. Hence, we have the digits 2 + 5 + 1 + 5 = 13. Therefore, the sum of the digits in the number 2515 is 13.

Math question: If 2515 is divided by the sum of its digits squared minus the product of its digits, what is the result?

Let's break down the question. The sum of the digits of 2515 is 2 + 5 + 1 + 5 = 13. The product of the digits is 2 * 5 * 1 * 5 = 50. Thus, the denominator is 13^2 - 50 = 169 - 50 = 119. Now, divide 2515 by 119: 2515 ÷ 119 = 21.17 (to 2 decimal places). Therefore, the result is approximately 21.17.

Question: What is the sum of the number 2515 squared and the square root of 2515 multiplied by its cube root, subtracted by the product of 2515 divided by the square root of 2515 and the cube root of 2515, rounded to the nearest hundredth?

To solve this equation, we start by computing 2515 squared, which results in 6,327,225. Next, we find the square root of 2515, which is approximately 50.15, and multiply it by the cube root of 2515, approximately 13.94. Their product is 699.79. Then, we divide 2515 by the square root of 2515, approximately 50.15, and multiply it by the cube root of 2515, approximately 13.94. This gives us 27.88. Lastly, we subtract 27.88 from 699.79, resulting in 671.91. Rounding this value to the nearest hundredth, we get 671.91. Therefore, the answer is approximately 671.91.
