Math question: How many different factors does the number 980 have?

To find the number of factors, let's prime factorize 980: 2^2 * 5 * 7^2. Any factor of 980 can be formed by selecting powers of each prime factor. The exponent of 2 can be 0, 1, or 2; the exponent of 5 can be 0 or 1; and the exponent of 7 can be 0, 1, or 2. Therefore, the number of factors = (2+1) * (1+1) * (2+1) = 3 * 2 * 3 = 18. Hence, the number 980 has 18 different factors.

Math question: What is the square root of the sum of 980 divided by the product of its digits, when rounded to the nearest whole number?

To find the square root, start by dividing 980 into its digits, which are 9, 8, and 0. The product of these digits is 9 * 8 * 0 = 0. Now, divide 980 by the product, which equals 0 / 0 since division by zero is undefined. Therefore, the question is invalid as it leads to an undefined result.

Math question: What is the sum of the squares of the first 10 positive integers, when multiplied by 2 and divided by 5, plus the product of 980 and the square root of 2?

The sum of the squares of the first 10 positive integers is 385. Multiplying this by 2 gives 770, and dividing it by 5 results in 154. Additionally, the product of 980 and the square root of 2 is approximately 1385. Therefore, the total is 154 + 1385, which equals 1539.
