Math Question: If the number 9857 is multiplied by 3 and then divided by its square root, what is the result?

To find the result, we first multiply 9857 by 3, which gives 29571. Then we calculate the square root of 9857, which is approximately 99.28. Dividing 29571 by 99.28, we get the result as approximately 297.69. Therefore, multiplying 9857 by 3 and then dividing by its square root gives a result of approximately 297.69.

Question: Find the sum of all prime numbers less than 9857 that are divisible by 4 but not divisible by 7.

To solve this, we start by listing all prime numbers less than 9857, which are divisible by 4 but not divisible by 7: 29, 89, 109, 149, 229, 269, 389, 409, 449, 509, 569, 809, 929, 1109, 1289, 1309, 1429, 1489, 1609, 1789, 1889, 1949, 2029, 2089, 2249, 2549, 2669, 2849, 2969, 3089, 3349, 3389, 3469, 3529, 3769, 3929, 4009, 4249, 4489, 4709, 4949, 5089, 5309, 5569, 5629, 5749, 5789, 5869, 5929, 5989, 6169, 6269, 6569, 6749, 6869, 6989, 7289, 7349, 7549, 7609, 7649, 7829, 7889, 8009, 8249, 8629, 8689, 8789, 8929, 9049, 9209, 9329, 9469, 9689, 9809. Adding them all up, we get a sum of 283,706. Therefore, the sum of all prime numbers less than 9857 that are divisible by 4 but not divisible by 7 is 283,706.

Math Question: If I multiply the number 9857 by 23 and then subtract 7896, what is the result?

To find the answer, we need to perform the following calculation: (9857 * 23) - 7896. Multiplying 9857 by 23 gives 226411, and subtracting 7896 from it yields 218515. Hence, the result of the given calculation is 218515.
