Math question: What is the sum of the three prime factors of 1778?

To find the prime factors of 1778, we divide it by the smallest prime number, 2. Consequently, 1778 ÷ 2 = 889. Now, 889 is not divisible by 2 anymore, so we move on to the next prime number, 3. Dividing, we get 889 ÷ 3 = 296.3(.3 representing that it is not exactly divisible by 3). Continuing, 296 ÷ 2 = 148, 148 ÷ 2 = 74, 74 ÷ 2 = 37. Hence, the prime factors of 1778 are 2, 2, and 37. Now, we sum these prime factors: 2 + 2 + 37 = 41. Thus, the sum of the three prime factors of 1778 is 41.

Math question: What is the sum of the digits of the number 1778 multiplied by its quotient when divided by 9 minus the product of its tens digit and the square root of its units digit?

To find the sum of the digits of 1778, we add 1 + 7 + 7 + 8 = 23. When we divide 1778 by 9, we get a quotient of 197.555..., rounded to 3 decimal places. Multiplying this quotient by the sum of the digits (23) gives us 4533.67. Now, let's calculate the product of the tens digit (7) and the square root of the units digit (√8 ≈ 2.828): 7 * 2.828 = 19.796. Finally, subtracting the product obtained from the previous calculation from 4533.67, we get the answer: 4513.874.

Question: Find two consecutive even numbers such that their sum is 1778.

Let's represent the smaller even number as x. The next consecutive even number can then be represented as (x + 2). According to the given condition, the sum of these two numbers is 1778. Therefore, we can set up the equation x + (x + 2) = 1778. Simplifying the equation, we have 2x + 2 = 1778. Subtracting 2 from both sides gives 2x = 1776. Dividing both sides by 2, we find x = 888. Thus, the two consecutive even numbers are 888 and 890, with their sum equal to 1778.
