Math question: What is the sum of the digits when the number 1287 is squared and divided by the cube of 3?

To calculate this, we first need to square 1287, which equals 1,660,569. Then, we find the cube of 3, which equals 27. Now, let's divide 1,660,569 by 27, which gives us 61,502. Finally, summing the individual digits of 61,502, we get 6 + 1 + 5 + 0 + 2 = 14. Therefore, the sum of the digits when 1287 is squared and divided by the cube of 3 is 14.

Math Question: If Jane divides the number 1287 by 3, squares the quotient, and then adds 50, what is the result?

To find the result, we need to divide 1287 by 3, which equals 429. Next, we need to square 429, which gives us 184041. Finally, adding 50 to 184041, we obtain the result of 184091. Therefore, the final answer after performing the operations is 184091.

Math Question: What is the remainder when 1287 is divided by the sum of its digits squared?

To find the sum of the digits, we have 1 + 2 + 8 + 7 = 18. Squaring 18 gives us 324. Now, we divide 1287 by 324. The quotient is 3, and the remainder is 315. Hence, the remainder when 1287 is divided by the sum of its digits squared is 315.
