N°25  A= racine(3² x 3) / racine(3) = 3xracine(3) / racine (3) = 3
B =racine( 2² x 2 x 3²) / racine(2) = 2 x 3 x racine(2) / racine (2) = 2 x 3 = 6
C = racine( 3 x 2 x 3²) / racine(2) = 3 x racine(3) x racine(2) / racine(2) = 3 x racine(3)

A= racine(2 x 7²) / racine(2) = 7 x racine(2) / racine(2) = 7
B=racine(6 x 3²) / racine(6) = 3 x racine(6) / racine(6) = 3
C= racine(5 x 5²) / racine(5) = 5 x racine(5) / racine(5) = 5
