Odpowiedź:
a) 2^2 + x^2 = (√24)^2
4 + x^2 = 24
x^2 = 20
x = √20 = 2√5
c) 3^2 + (3√7)^2 = x^2
9 + 63 = x^2
72 = x^2
√72 = 6√2 = x
b) x^2 + 5^2 = 7^2
x^2 + 25 = 49
x^2 = 24
x = √24 = 2√6
d) 6^2 + (2√3)^2 = x^2
36 + 12 = x^2
√48 = 4√3= x
e) 6^2 + 4^2 = x^2
36 + 16 = x^2
√52 = 2√13 = x
f) (2√5)^2 + x^2 = (2√19)^2
20 +x^2 = 76
x^2 = 56
x = √56 = 2√14
