Răspuns :

a)=

[tex]2 \times 2 + 2 = 4 + 2 = 6[/tex]

b)=

[tex]28 \sqrt{2} + \sqrt{13} + 85[/tex]

c)=

[tex]8 \times 36 \times 27 = 7776[/tex]

d)=

[tex] \frac{8 + 5 + 5}{10} = \frac{18}{10} = \frac{9}{5} [/tex]

e)=

[tex] \sqrt{5} + 9 \times 3 \sqrt{2} = \sqrt{5} + 27 \sqrt{2} [/tex]

f)=

[tex]2x \times (1 + 2y)[/tex]
