Question

Please butuh banget bantuan kalian...
1. (2√3 + 3√2)2 =
2. (5√2 - 2)2 =
3. (√3 - √5)2 =
4. (2√6 - √5)2 =

Answer 1

1.) (2√3+3√2)²= (2√3+3√2)(2√3+3√2) = 12 + 18 + 12√6 = 30 + 12√6
2.) (5√2-2)²= (5√2-2)(5√2-2)= 50 + 4 -20√2 = 54 - 20√2
3.) (√3-√5)² = (√3-√5)(√3-√5) = 3+5 -2√15 = 8-2√15
4.) (2√6-√5)² = (2√6-√5)(2√6-√5) = 24+5 - 4√30 = 29 - 4√30

Semoga membantu
