Question

M=10 mũ 2 -[60:(5 mũ 4 : 5 mũ 2-3 . 5)]

Answer 1

\(=10^2-\left[60:\left(5^2-15\right)\right]=100-6=94\)

Answer 2

\(M=10^2-\left[60:\left(5^4:5^2-3.5\right)\right]\)

\(M=10^2-\left[60:\left(5^2-15\right)\right]\)

\(M=10^2-\left[60:10\right]\)

\(M=10^2-6\)

\(M=100-6\)

\(M=94\)

Answer 3

`M=10^2 - [60 : (5^4 : 5^2 - 2-3.5)]`

`M=100 - [60 : ( 5^2- 2-3.5)]`

`M=100 - [60 : (25 - 2-15)]`

`M=100-[60 : (23-15)]`

`M=100-[60 : 6]`

`M=100 -6`

`M=94`
