Answer 1

Răspuns:

Explicație pas cu pas:

(3 - √2)^2 = 9 + 2 - 6√2 = 11 - 6√2

(2 - √3)^2 = 4 + 3 - 4√3 = 7 - 4√3

(4 + √2)^2 = 16 + 2 + 8√2 = 18 + 8√2

_______

(4 - √3)^2 = 16 + 3 - 8√3 = 19 - 8√3

(5 - √2)^2 = 25 + 2 -10√2 = 27 - 10√2

(√5 + √3)^2 = 5 + 3 + 2√15 = 8 + 2√15

_________

(√5 - √2)^2 = 5 + 2 - 2√10 = 7 - 2√10

(√5 + √7)^2 = 5 + 7 + 2√35 = 12 + 2√35

(√3 + 2)^2 = 3 + 4 + 4√3 = 7 + 4√3

_________

(3 - √5)^2 = 9 + 5 -6√5 = 14 - 6√5

(√3 - √2)^2 = 3 + 2 - 2√6 = 5 - 2√6

(√6 + 2)^2 = 6 + 4 + 4√6 = 10 + 4√6

__________

(√6 - 3)^2 = 6 + 9 -6√6 = 15 - 6√6

(√5 - √6)^2 = 5 + 6 - 2√30 = 11 - 3√30

(2√3 - 1)^2 = 12 + 1 - 4√3 = 13 - 4√3

__________

(√3 - 2)(√3 + 2) + (√5 - 3)(√5 + 3) = 3 - 4 + 5 - 9 = 8 - 13 = -5

__________

(√6 - √3)(√6 + √3) - (√6 - √10)(√6 + √10) = 6 - 3 - (6 - 10) = 3 - 6 + 10 = 7
