Exercice 3
3/7 * [tex] (7/3)^{3} [/tex] = [tex] (7/3)^{5} [/tex]
Exercice 5
A= [tex] \frac{ \frac{2}{3}+ \frac{1}{6} }{2- \frac{1}{2} } [/tex]
A= [tex] \frac{ \frac{4}{6}+ \frac{1}{6} }{ \frac{4}{2}+ \frac{1}{2} } [/tex]
A= [tex] \frac{ \frac{5}{6} }{ \frac{5}{2} } [/tex]
B= 3/4 + 1/2 *( 2/3 -1)
B= 3/4 + 2/6 -1/2
B= 3/4 + 1/3 -1/2
B= 9/12 +4/12 -1/2
B= 13/12 -1/2
B= 13/12 - 6/12
B= 7/12
