Akar 28 + 2 akar 63 – akar 700
aljabar √28 + 2√63 - √700 = √(4 × 7) + 2√(9 × 7) - √(100 × 7) = 2√7 + 2 . 3√7 - 10√7 = (√7)(2 + 6 - 10) = (√7) × (-2) = -2√7
aljabar
√28 + 2√63 – √700
= √(4 × 7) + 2√(9 × 7) – √(100 × 7)
= 2√7 + 2 . 3√7 – 10√7
= (√7)(2 + 6 – 10)
= (√7) × (-2)
= -2√7

8√27 / 6√3
= 8/6 × √(27/3)
= 8/6 × √9
= 8/6 × 3
= 8/2
= 4
