Question

50-[(50-2 mũ 3.5):2+3]

Answer 1

\(50-\left[\left(50-2^3.5\right):2+3\right]=50-\left[\left(2.5^2-2^3.5\right):2+3\right]=50-\left[\left(2.5\right):2+3\right]=50-8=42\)

Answer 3

\(50-\left[\left(50-2^3.5\right):2+3\right]\)

\(=50-\left[\left(50-8.5\right):2+3\right]\)

\(=50-\left[\left(50-40\right):2+3\right]\)

\(=50-\left[10:2+3\right]\)

\(=50-\left[5+3\right]\)

\(=50-8=42\)

 

Answer 4

\(50-\left[\left(50-2^3.5\right):2+3\right]\) 

\(=50-\left[\left(50-8.5\right):2+3\right]\) 

\(=50-\left[\left(50-40\right):2+3\right]\) 

\(=50-\left[10:2+3\right]\) 

\(=50-\left[5+3\right]\) 

\(=50-8\) 

\(=42\)
