Math question: If a rectangle has a length of 40 units and a width of 40 units, what is the area of the rectangle?

To find the area of a rectangle, multiply the length by the width. In this case, the length is 40 units and the width is also 40 units. Therefore, the area of the rectangle is 40 units × 40 units = 1600 square units.

Math question: Find the square root of the sum of the factors of 1600, excluding 1 and 1600, divided by the average of the prime numbers between 31 and 100.

To solve this question, we start by finding the factors of 1600, excluding 1 and 1600, which are 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 64, 80, 100, 160, 200, 320, 400, 800. Summing these factors gives us 3894. Next, we need to find the average of the prime numbers between 31 and 100. These primes are 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and 97. Their average is calculated as (31+37+41+43+47+53+59+61+67+71+73+79+83+89+97)/15 = 65.267. Finally, we take the square root of the sum of the factors, 3894, and divide it by the average of the primes, 65.267. The result is √3894 / 65.267 ≈ 8.287. Hence, the answer is approximately 8.287 (rounded to three decimal places).

What is the square root of 1600 multiplied by the cube root of 1600, divided by the logarithm of 1600 to the base 10? Use three decimal places for your answer.

The square root of 1600 is 40, the cube root of 1600 is 11.467, and the logarithm of 1600 to the base 10 is 3.204. Therefore, (40 * 11.467) / 3.204 ≈ 143.513.
