Question

urgent am nevoie de ex5.​

Answer 1

$ma = \frac{a + b}{2} = \frac{ - 4 \sqrt{2} + 14 \sqrt{2} }{2} = \frac{10 \sqrt{2} }{2} = 5 \sqrt{2} - > corina$

$\sqrt{8} = 2 \sqrt{2}$

$\sqrt{18} = 3 \sqrt{2}$

$\sqrt{32} = 4 \sqrt{2}$

$a = 2 \sqrt{2} - 6 \sqrt{2} = - 4 \sqrt{2}$

$b = 12 \sqrt{2} + 2 \sqrt{2} = 14 \sqrt{2}$
