Uiteee sper ca te am ajutattt

Answer 2

Răspuns:

$= (\frac{2}{10})^{3} -\frac{1}{5^{3} } +\frac{1}{10} =\frac{2^{3} }{10^{3} } -\frac{1}{5^{3} } +\frac{1}{10}=$

aducem primele doua fractii la acelasi numitor comun:

c.m.m.m.c. ($10^{3}$, $5^{3}$) = $10^{3}$

amplificam a doua fractie cu $10^{3} :5^{3} =2^{3}$ si avem:

$= \frac{2^{3} }{10^{3} } -\frac{2^{3} }{10^{3} } +\frac{1}{10} =\frac{1}{10}$
