Odpowiedź:
d ) c = ( 3 [tex]\frac{2}{6} + 87 \frac{5}{6} ): 2 = 91\frac{1}{6} : 2 = 45 \frac{7}{12}[/tex]
d = 87 [tex]\frac{10}{12} - 45\frac{7}{12} = 42\frac{3}{12} = 45\frac{1}{4}[/tex]
-------------------------------------------------------------
e ) c = ( - 3√7 + ( - 29√7 ) : 2 = - 32√7 : 2 = - 16√7
d = - 16√7 - ( - 29√7 ) = 13√7
-------------------------------------------
f ) c = ( - 9 + 4√5 + 5 - 2√5 ) : 2 = ( - 4 +2√5 ) : 2 = - 2 + √5
d = 5 - 2√5 - ( -2 + √5 ) = 7 - 3√5
