Answer 1

Răspuns:

1

Explicație pas cu pas:

1. $=2\sqrt{2}+\sqrt{2}-3\sqrt{2}=0$

2. $=18\sqrt{3*5}=18\sqrt{15}$

3. $=-3\sqrt{4}=-3\sqrt{2^{2} }= -3*2=-6$

4. $=16*3=48$

B.  $m=\frac{a+b}{2}$

1.$m=\frac{3+7}{2} =\frac{10}{2} =5$

2.$m=\frac{\frac{4}{3}+\frac{1}{3} }{2}=\frac{\frac{5}{3} }{2} =\frac{5}{3}*\frac{1}{2}=\frac{5}{6}$
