Question: If the number 8422 is multiplied by 7, then divided by 2, what would be the sum of the result and the difference between 8422 and the square of its square root?

To find the square root of 8422, we know that its approximate value is around 91.78. Squaring this value gives us 8425.1684. The difference between 8422 and 8425.1684 is approximately -3.1684. Multiplying 8422 by 7 gives us 58954, and dividing it by 2 yields 29477. Adding 29477 and -3.1684 gives us a final answer of approximately 29473.8316.

What is the sum of the digits in the number 8422 when each digit is squared and then added together?

To find the sum of the squared digits in the number 8422, we take each digit and square it: 8^2 + 4^2 + 2^2 + 2^2 = 64 + 16 + 4 + 4 = 88. Therefore, the sum of the squared digits in 8422 is 88.

What is the smallest whole number that when multiplied by 8422 results in a perfect square?

To find the smallest whole number that makes 8422 a perfect square, we need to factorize 8422. It can be written as 2^1 * 7^1 * 601^1. To form a perfect square, each prime factor's exponent needs to be even. The smallest exponent that makes 2 to the power of that exponent greater than or equal to 1 is 2. Similarly, both 7 and 601 need to have even exponents. So, the smallest whole number is 2^2 * 7^2 * 601^2 = 118569204. Multiplying 8422 by this number results in a perfect square.
