Calculati suma dintre numarul x si opusul numarului y
X=-3spra4 ;y=-1spra5

Răspuns :


[tex]\it x = - \dfrac{3}{4} \\\;\\ \\\;\\ y = - \dfrac{1}{5} \Rightarrow\ opusul\ lui\ y\ este\ y' =\dfrac{1}{5} \\\;\\ \\\;\\ x+y' = -\dfrac{^{5)}3}{\ 4}+\dfrac{^{4)}1}{\ 5} =\dfrac{-15+4}{20} =\dfrac{-11}{20} =-\dfrac{11}{20} [/tex]
