Exercice 9
soit \(a, b\) deux réels positifs non nuls , simplifier : \(A=\sqrt{\frac{25 a^2}{9}}\)\(B=\frac{1}{\sqrt{b}} \cdot \sqrt{\frac{b}{a}} \cdot \sqrt{b a}\)\(C=\sqrt{\frac{b}{a}} \cdot \sqrt{b^2 a} \cdot \frac{1}{\sqrt{b}}\)\(D=\sqrt{b^3} \sqrt{a b} \cdot \sqrt{b}\)\(E=\frac{\sqrt{b a^3} \cdot \sqrt{a b^2} \cdot \sqrt{(a b)^5}}{\sqrt{a b^4} \cdot \sqrt{b a^6}}\)
