Salut!

a) $\frac{3}{10} si \frac{4}{5} ^{(2} => \frac{3}{10} si \frac{4*2}{5*2} => \frac{3}{10} si \frac{8}{10}$

b) $\frac{3}{4}^{(3} si \frac{12}{5} => \frac{3*3}{4*3} si \frac{5}{12} => \frac{9}{12} si \frac{5}{12}$

c) $\frac{2}{15} si \frac{8}{3} ^{(5} => \frac{2}{15} si \frac{8*5}{3*5} => \frac{2}{15} si \frac{40}{15}$

d) $\frac{7}{6}^{(3} si \frac{5}{18} => \frac{7*3}{6*3} si \frac{5}{18} => \frac{21}{18} si \frac{5}{18}$

Succes!
