Math question: What is the sum of the first 20 positive odd numbers after 7810?

To find the sum of the first 20 positive odd numbers after 7810, we have to determine the value of the 21st odd number after 7810, which is 7810 + 2 × 20 = 7850. The sum of the first 20 positive odd numbers can be calculated using the formula: S = (n/2)(2a + (n-1)d), where S is the sum, n is the number of terms, a is the first term, and d is the common difference. Here, a = 7811 (smallest odd number after 7810), n = 20, and d = 2. Substituting the values, we get S = (20/2)(2(7811) + (20-1)(2)), which simplifies to S = 10(15622 + 38) = 156600. Therefore, the sum of the first 20 positive odd numbers after 7810 is 156600.

Math question: If we divide the number 7810 by 5, what is the remainder?

To find the remainder, we use the modulo operator (%). When we divide 7810 by 5, the remainder is 0 since 7810 is evenly divisible by 5.

Math question: What is the value of 7810 when squared and then divided by the sum of its digits, multiplied by the square root of its middle two digits, subtracted by the product of its first and last digit, and finally added to the cube of its last digit?

To solve the equation, we first calculate the sum of the digits, which is 7 + 8 + 1 + 0 = 16. Next, the square root of the middle two digits, 8 and 1, is √(81) = 9. Then, multiplying the square root by the sum, we obtain 9 * 16 = 144. Now we subtract the product of the first and last digit, which is 7 * 0 = 0. After that, we add the cube of the last digit, which is 0^3 = 0. Finally, we sum all the results: 7810^2 / 16 - 0 + 0 = 61,240,100 / 16 = 3,827,506 and 1/4. Therefore, the value of the equation is 3,827,506 and 1/4.
