Tolong dijawab ya... penting... saya hanya bingung jawaban saya betul atau tidak... jadi tolong dijawab ya... makasih

BC^2 = AB^2 + AC^2
BC^2 = (6 + √2)^2 + (6 - √2)^2
BC^2 = 36 + 12√2+ 2 + 36 - 12√2 + 2
BC^2 = 36 + 36 + 2 +2
BC^2 = 76
BC = √76
BC = √(4 × 19)
BC = √4.√19
BC = 2√19

BC = √(6 + √2)² + (6 - √2)²
BC = √(6 + √2) (6 + √2) + (6 - √2) (6 - √2)
BC = √(36 + 6√2 + 6√2 + 2 + 36 - 6√2 - 6√2 + 2)
BC = √(72 + 4)
BC = √76
BC = √19 x √4
BC = 2 √19

Semoga Membantu!!!
