Question

Упростить выражение ( √11 + √5) (√11-√5)​

Answer 1

$(\sqrt{11}+\sqrt{5})(\sqrt{11}-\sqrt{5})=(\sqrt{11})^{2}-(\sqrt{5})^{2}=11-5=6$

Answer 2

Ответ:здесь формула а²-b²= (a-b)(a+b)

(√11+√5)(√11-√5)= (√11)²-(√5)²= 11-5=6

Answer 3

To simplify the given expression ( √11 + √5) (√11 - √5), we can use the difference of squares formula, which states that (a + b)(a - b) = a^2 - b^2.

In this case, let's treat √11 as "a" and √5 as "b".

So, (√11 + √5) (√11 - √5) = (√11)^2 - (√5)^2

Now, calculate:

(√11)^2 = 11 (√5)^2 = 5

Now, the simplified expression is:

11 - 5 = 6

Therefore, the simplified form of ( √11 + √5) (√11 - √5) is 6.
