Answer 1

Ответ:

(k-n) в о второй степени

Answer 2

To simplify the expression (k - n)(k - n), you can expand it using the distributive property of multiplication. Let's go through the steps:

Step 1: Distribute the first term, k, to both terms inside the second parentheses: (k - n)(k - n) = k(k - n) - n(k - n)

Step 2: Distribute k to both terms inside the second parentheses: k(k - n) - n(k - n) = k * k - k * n - n * k + n * n

Step 3: Simplify each term: k * k is k^2 -k * n is -kn -n * k is -kn n * n is n^2

Step 4: Combine like terms: k^2 - kn - kn + n^2 = k^2 - 2kn + n^2

So, (k - n)(k - n) simplifies to k^2 - 2kn + n^2.
