Math question: What is the sum of the digits of the number 7717?

To find the sum of the digits, we add each digit together. So, 7 + 7 + 1 + 7 = 22.

What is the sum of the digits in the number 7717 when multiplied by the square root of 7717 and divided by the difference between 7717 and its reverse, rounded to the nearest whole number?

To find the sum of the digits, we have 7 + 7 + 1 + 7 = 22. The square root of 7717 is approximately 87.88. The reverse of 7717 is 7177. The difference between 7717 and 7177 is 540. When we divide 87.88 by 540, we get approximately 0.1628. Rounding this to the nearest whole number gives 0. The sum of the digits, multiplied by the square root and divided by the difference rounded to the nearest whole number is 22 * 87.88 / 540 ≈ 3.557.

What is the sum of the digits of the number 7717, when each digit is squared, multiplied by 2, then multiplied by 3, and finally divided by 4?

To find the sum of the digits of the number 7717, we square each digit: 7² = 49, 7² = 49, 1² = 1, 7² = 49. Then, multiplying each squared digit by 2 gives us: 49*2 = 98, 49*2 = 98, 1*2 = 2, 49*2 = 98. Next, we multiply each result by 3: 98*3 = 294, 98*3 = 294, 2*3 = 6, 98*3 = 294. Finally, dividing each value by 4 yields: 294/4 = 73.5, 294/4 = 73.5, 6/4 = 1.5, 294/4 = 73.5. Finally, adding up these results, we get: 73.5 + 73.5 + 1.5 + 73.5 = 222. Hence, the sum of the digits of the number 7717, when each digit is squared, multiplied by 2, then multiplied by 3, and finally divided by 4, is 222.
