Math Question: What is the sum of all the odd numbers from 1 to 243?

To find the sum of the odd numbers, we utilize the formula for the sum of an arithmetic series. The first term (a) is 1, the last term (l) is 243, and the common difference (d) is 2 since we are adding odd numbers. Using the formula: Sn = (n/2) * (a + l), where Sn represents the sum of n terms, plug in the values. The number of terms (n) can be found using the formula n = (l - a)/d + 1. For the given series, n = (243 - 1)/2 + 1 = 122.5 + 1 = 123. Substitute the values to find the sum: Sn = (123/2) * (1 + 243) = 61.5 * 244 = 14,994. Therefore, the sum of all the odd numbers from 1 to 243 is 14,994.

Math question: What is the sum of all digits in the number 243?

To find the sum of all digits in 243, we need to add the individual digits. The number 243 can be written as 2 + 4 + 3. Thus, the sum is 9.

Math question: What is the square root of 243 raised to the power of 4, divided by the cube of 3?

To find the square root of 243, we get √243 = 15.588. Then, raising it to the power of 4, we have 15.588^4 = 16948.744. Next, we cube 3, which is 3^3 = 27. Finally, dividing 16948.744 by 27, the result is 627.352. Therefore, the answer is 627.352.
