Dacă a=1/2-1/3,calculati a la puterea a3a

Răspuns :

a=1/2-1/3 aducem la acelasi numitor
a=3/6-2/6
a=1/6
a^3=(1/6)^3
a^3=1/216
a=[tex] \frac{1}{2} - \frac{1}{3} [/tex]
a= [tex] \frac{3}{6} - \frac{2}{6} [/tex]
a=[tex] \frac{1}{6} [/tex]
[tex]
{a}^{2} [/tex]=[tex] { \frac{1}{6} }^{2} [/tex]
[tex]
{a}^{2} [/tex]=[tex] \frac{1}{36} [/tex]
