Răspuns: [tex]\red{\bf x= -2}[/tex]
Explicație pas cu pas:
[tex]\bf x =\bigg\{\big(-1\big)^{11}-\Big[\big(-7\big)\cdot\big(-7\big)^2\Big]^{3}:(-7)^7\bigg\}:\big(-5\big)^2[/tex]
[tex]\bf x =\bigg\{-1-\Big[\big(-7\big)^{1+2}\Big]^{3}:(-7)^7\bigg\}:\big(-5\big)^2[/tex]
[tex]\bf x =\bigg\{-1-\Big[\big(-7\big)^{3}\Big]^{3}:(-7)^7\bigg\}:\big(-5\big)^2[/tex]
[tex]\bf x =\Big[-1-\big(-7\big)^{3\cdot3}:(-7)^7\Big]:\big(-5\big)^2[/tex]
[tex]\bf x =\Big[-1-\big(-7\big)^{9}:(-7)^7\Big]:\big(-5\big)^2[/tex]
[tex]\bf x =\Big[-1-\big(-7\big)^{9-7}\Big]:25[/tex]
[tex]\bf x =\Big[-1-\big(-7\big)^{2}\Big]:25[/tex]
[tex]\bf x =\big(-1-49\big):25[/tex]
[tex]\bf x =-50:25\implies \boxed{\bf x= -2}[/tex]
