Answer 1

Ответ:

Объяснение:

(√7+√11)²= (√7)²+2*√7*11+(√11)²= 7+2√77+11= 18+2√77

Answer 2

(√7+√11)²=7+2√77+11=18+2√77=

=2(9+√77)

Answer 3

Let's first expand the expression (√7+√11)^2 using the formula for the square of a binomial:

(a + b)^2 = a^2 + 2ab + b^2

In this case, we have:

(a, b) = (√7, √11)

So, applying the formula, we get:

(√7+√11)^2 = (√7)^2 + 2(√7)(√11) + (√11)^2 = 7 + 2√77 + 11 = 18 + 2√77

Therefore, (√7+√11)^2 = 18 + 2√77.
