Question

Media aritmetică a numerelor.​

Answer 1

Răspuns:

Explicație pas cu pas:

a)

3√3 + 7√3 - 16√3 = -6√3

media aritmetica = -6√3 : 3 = -2√3

b)

-3√5 + 10√5 + 4√5 = 11√5

media aritmetica = 11√5/3

c)

21√2 - 10√2 + √2 = 12√2

media aritmetica = 12√2 : 3 = 4√2

Answer 2

a) $\frac{3\sqrt{3} +7\sqrt{3} +(-16\sqrt{3} )}{3}$= $\frac{-6\sqrt{3} }{3}$=$-2\sqrt{3}$

b) $\frac{-3\sqrt{5}+10\sqrt{5} +4\sqrt{5}}{3}$=$\frac{11\sqrt{5} }{3}$

c) $\frac{21\sqrt{2}+(-10\sqrt{2})+ \sqrt{2} }{3}$=$\frac{12\sqrt{2} }{3}$=$4\sqrt{2}$
