Question

{[(-3 elevado a 3 ) 2 elevado a 2 + (-3)]+100}:a raiz quadrada de 121

Answer 1

{[(-3³)2²+(-3)]+100}÷√121
{[-27×4-3]+100}÷11
{-108-3+100)÷11
-11÷11=-1

Answer 2

{[( - 3³) 2² + (-3)] + 100 } : √121 =
= {[( - 27) 4 - 3)] + 100 } : 11
= {[( - 108 - 3)] + 100 } : 11
= { - 111 + 100 } : 11
= - 11 : 11
= - 1
