What is the sum of the digits of the number 6642 multiplied by the sum of the even digits of the number 6642, divided by the product of the prime factors of 6642?

To find the sum of the digits, we add 6 + 6 + 4 + 2 = 18. The even digits are 6 and 4, so their sum is 6 + 4 = 10. The prime factors of 6642 are 2, 3, and 19. Thus, the product of the prime factors is 2 × 3 × 19 = 114. Consequently, the final answer is (18 × 10) ÷ 114 = 1.58 (rounded to two decimal places).

What is the sum of the thousands digit and the hundreds digit of the number 6642 when multiplied by the difference between the tens digit and the units digit, divided by the square of the hundreds digit, divided by the product of the thousands digit and the units digit, multiplied by the tens digit?

To compute the answer, we first consider the given number. The thousands digit is 6, the hundreds digit is 6, the tens digit is 4, and the units digit is 2. Now, let's break down the computation according to the operations stated in the question: (i) Multiply the thousands and hundreds digit: 6 * 6 = 36 (ii) Find the difference between the tens and units digit: 4 - 2 = 2 (iii) Compute the square of the hundreds digit: 6^2 = 36 (iv) Calculate the product of the thousands and units digit: 6 * 2 = 12 (v) Combine the previous results, taking each operation in order: (36 + 2) / 36 / 12 * 4 (vi) Simplify the expression further: 38 / 36 / 12 * 4 = 0.2963 (rounded to 4 decimal places) Thus, the answer after evaluating the given mathematical expression is approximately 0.2963.

What is the sum of the digits in the number 6642?
