\(\text{5^2: 5 + (116 +72: 36): 4}\\ =5+\left(116+2\right):4\\=5+118:4 \\ =5+29,5=34,5\)

Answer 2

1, 5^2:5+(116+72:36):4

=5+118:4

Answer 3

\(100:\left\{250:\left[450-\left(4.5^3-6.5\right)\right]\right\}\\ =100:250:\left[450-\left(500-30\right)\right]\\ =100:250:\left[450-470\right]\\ =0,4:-20\\ =-0,02\)
