3² +x² = pier z 13 ²

a² + b² =c²
27+20=x²
47=x²
x= pierwiastek z 47
b=x
c=√13
3² + x² = (√13)²
9 + x² = 13
x² = 4
x = 2
a=3√3
b=2√5
c=x
(3√3)² + (2√5)² = x²
27 + 20 = x²
x² = 47
x = √47
Pozdrawiam :*
9 + x kw = 13 /-9
x kw = 4/pierwiastkujemy
x = √4
x = 2
3√3 kw + 2√5 kw = x kw
√27 kw + √20 kw = x kw
27 + 20 = x kw
47 = xkw/pierwistkujemy
√47 = x
kw to kwadrat bo mi nie wyskakuje :)
