Math question: What is the largest prime factor of the number 1251?

To find the largest prime factor of 1251, we need to factorize it. Dividing 1251 by 3 gives us 417. Upon calculating further, we find that 417 is divisible by 3, resulting in 139. Now, 139 is a prime number, thus it is the largest prime factor of 1251. So, the largest prime factor of 1251 is 139. Explanation: A prime factor is a prime number that divides a given number without leaving a remainder. To find the largest prime factor of 1251, we start by dividing it by the smallest prime number, 2. However, 1251 is odd, so it is not divisible by 2. Next, we divide by 3 and obtain 417. We continue dividing until we reach 139, which is a prime number and cannot be divided further. Therefore, 139 is the largest prime factor of 1251.

Math question: What is the cube root of 1251?

To find the cube root of 1251, we need to determine a number that, when multiplied by itself twice (i.e., cubed), results in 1251. By employing trial and error, we deduce that 11 is a close number, as 11*11*11 equals 1331, which is slightly larger than 1251. By decreasing it to 10, we find that 10*10*10 equals 1000, which is smaller than 1251. Thus, we can conclude that the cube root of 1251 is approximately 10. Therefore, cube root (1251) ≈ 10.

Math question: What is the square root of the sum of 1251 and the difference between 1251 and its square root?

To calculate, first find the square root of 1251, which is approximately 35.35534. Now subtract this square root from 1251: 1251 - 35.35534 = 1215.64466. Finally, add the original number and the difference together: 1251 + 1215.64466 = 2466.64466. Therefore, the answer is 2466.64466.
