Explicação passo-a-passo:
[tex]\sqrt{13^3+13^3+\dots+13^3}=13^3+13^3+13^3+13^3\ \therefore\\\\ \sqrt{n(13^3)}=4(13^3)\ \therefore\ \bigg(\sqrt{n(13^3)}\bigg)^2=\bigg(4(13^3)\bigg)^2 \ \therefore[/tex]
[tex]n(13^3)=4^2(13^3)^2\ \therefore\ n=\dfrac{16(13^6)}{13^3}\\\\ \therefore\ n=16(13^3)\ \therefore\ \boxed{n=35152}[/tex]
