Question

4-{(-2)²×(-3)-[-√121+(-3)×(-4)]-(-1)}

Answer 1

4 - {(-2)² * (-3) - [ -√121 + (-3) * (-4)] - (-1)} =
4 - {4 * (-3) - [ -11 + (12)] + 1} =
4 - { -12 - [1] + 1} =
4 - { -12} =
4 + 12 =
16

Answer 2

4-{(-2)²×(-3)-[-√121+(-3)×(-4)]-(-1)}= 4-{4×(-3)-[-11+12]+1} 4-{-12-[1]+1} 4-{-13+1} 4-{-12} 4+12 16
