What would be the sum of the digits when we multiply 542 by its square root and then subtract its cube root?

First, the square root of 542 is approximately 23.25. Next, the cube root of 542 is approximately 8.23. Multiplying 542 by its square root gives us 12593.5, and subtracting the cube root gives us 12585.27. Finally, summing the digits 1+2+5+8+5+2+7 gives us 30. Therefore, the sum of the digits when we multiply 542 by its square root and subtract its cube root is 30.

Math question: What is the sum of all even numbers from 2 to 542, inclusive?

To find the sum, we first determine the number of even integers in the given range. The last even number in the range is 542 itself. So, to find the count, we divide 542 by 2 (since every second number is even) and add 1 to account for the inclusive range. This gives us (542 ÷ 2) + 1 = 272. Now, we have an arithmetic sequence starting from 2 with a common difference of 2, in which the last term is 542. Using the formula for the sum of an arithmetic sequence, the sum S can be calculated as S = (n/2)(first term + last term), where n is the number of terms. Therefore, S = (272/2)(2 + 542) = (136)(544) = 73,984. So, the sum of all even numbers from 2 to 542 is 73,984.

Math question: What is the remainder when 542 is divided by 6?

To find the remainder when 542 is divided by 6, we divide 542 by 6 which gives us 90.3333. By rounding this down to the nearest whole number, we get 90. Multiplying 90 by 6, we obtain 540. Subtracting 540 from 542 leaves us with a remainder of 2. Hence, the remainder when 542 is divided by 6 is 2.
