Question

Cho n lớn hơn hoặc bằng 0 chứng minh căn bậc hai của n cộng căn bậc hai của n+2 nhỏ hơn 2 nhân căn bậc 2 của n +1

Answer 1

Answer:

I might not understand your question so I tried my best hopefully this would be your answer

Step-by-step explanation:

If a number n is not a prime, it can be factored into two factors a and b:

n = a * b

Now a and b can't be both greater than the square root of n, since then the product a * b would be greater than sqrt(n) * sqrt(n) = n. So in any factorization of n, at least one of the factors must be smaller than the square root of n, and if we can't find any factors less than or equal to the square root, n must be a prime.
