Explicație pas cu pas:

[tex]\bf \big(5^2+10\cdot 5^2\big):11=[/tex]

[tex]\bf 5^{2}\cdot\big(5^{2-2}+10\cdot 5^{2-2}\big):11=[/tex]

[tex]\bf 5^{2}\cdot\big(5^{0}+10\cdot 5^{0}\big):11=[/tex]

[tex]\bf 5^{2}\cdot\big(1+10\cdot 1\big):11=[/tex]

[tex]\bf 5^{2}\cdot\big(1+10\big):11=[/tex]

[tex]\bf 5^{2}\cdot11:11=\red{\underline{~5^{2}}}[/tex]
