a) (3)2 + (5)2= (x)2
9+25=(x)2
(X)2= 34
x= pierw z 34
b) (4)2 + (7)2 = (x)2
16+ 49 = (x)2
(x)2 = 65
x = pierw z 65
c) (4)2 + (y)2 = (4 pierw z 5)2
16 + (y)2 = 80 | -16
(y)2 = 64
y = 8
D) (2)2 + (y)2 = (2 pierw z 17)2
4 + (y)2 = 68 | -4
(y)2 = 64
y= 8
2.
a) (4 pierw z 3)2 + (a)2 = (3 pierw z 7)2
48 + (a)2 = 63 | -48
(a)2 = 15
a= pierw z 15
b) (5)2 + (2 pierw z 6)2 = (b)2
25 + 24 = (b)2
(b)2 = 49
b = 7
Te 2 po nawiasach to kwadrat i liczb nie trzeba zapisywać w nawiasach.
Mam nadzieję, że pomogłam i liczę na naj <3
