Math question: What is the square root of the sum of the digits of the number obtained by multiplying 2012 by its reverse?

To find the answer, we first need to multiply 2012 by its reverse, which is 2102. The product is 4235024. Now, we sum the digits: 4 + 2 + 3 + 5 + 0 + 2 + 4 = 20. Taking the square root of 20 gives us an approximate value of 4.47 (rounded to two decimal places). Therefore, the square root of the sum of the digits is approximately 4.47.

Math question: What is the smallest prime number greater than 2012?

To find the smallest prime number greater than 2012, we start by checking if 2013 is prime. Dividing 2013 by integers from 2 to its square root (√2013 ≈ 44.87) yields remainders. Therefore, we continue checking 2014, 2015, and so on until we find a prime number. After some calculations, the next prime is 2017, making it the smallest prime number greater than 2012.

Question: How many even numbers are there between 2012 and 1?

To find the number of even numbers between two numbers, we subtract the count of odd numbers from the total count of numbers. Between 1 and 2012, there are 2012 - 1 + 1 = 2012 numbers. Now, let's find the count of odd numbers between 1 and 2012. Since the first odd number is 1, we divide 2012 by 2 (each pair of numbers has one even and one odd) and round down to get 1006. Therefore, there are 2012 - 1006 = 1006 even numbers between 2012 and 1.
