Szczegółowe wyjaśnienie:
1
A) 6√3 /2 = 3√3
B) (2√3 · √3)/2 = 6/2 = 3
C) (4√21 · √3)/2 = 4√63 / 2 = 4 · 3 · √6 / 2= 12√6/2 = 6√6
2
P = ((3√3)²·√3) / 4 = 27√3 / 4
3
A) 3√2
B) 5
C) 2√6 / √2 = 2√12 / 2 = √12 = 2√3
4
A) 3√3 = a√3 / 2 -> 6√3 = a√3 -> a = 6
B) 9√3 = (a²√3) /4 -> 36√3 = a²√3 -> a² = 36 -> a = 6
C) 15 = a√3 / 2 -> 30 = a√3 -> 30 / √3 = a -> 30√3 / 3 = a -> a = 10√3
