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