a) Vis at \( \sqrt{12} \) kan omforms til \( 2 \sqrt{3} \)

40) Resolver los sfrulentes calculos comb a) \( (4 / 5-1 / 2)^{2} \cdot 25 / 3-\sqrt{1-7 / 16}= \) b) \( \sqrt{125 / 64}-(4 / 15: 8 / 5+1 / 3)^{1}= \) c) \( \sqrt{49 / 121}+(2 / 3: 1 / 9)^{2}= \) d) \( \sqrt{8 / 125}+(1 / 2+1-2 / 3)= \) e) \( (3 / 5)^{2}: 12 / 25+\sqrt{7 / 3-5 / 9}= \)

Find the outer measure of \( x \) for \( \{-5 \leq x \leq 3\} \cup\{-2 \leq x<7\} \)

5. ¿Cuál es el valor de \( \log _{4} \frac{1}{16} \) ?

(1) Comparer: \( 4 \sqrt{5} \) et \( 6 \sqrt{2} \) puis en déduire une comparaison de: \( 7-4 \sqrt{5} \) et \( 7-6 \sqrt{2} \)
