Question

2².5[(5²+2³):11-2]-3².2

Answer 1

`2^2 . 5 [(5^2 + 2^3 ) : 11 - 2 ] - 3^2 . 2`

`=4 . 5 [ ( 25 + 8 ) : 11 - 2 ] - 9 . 2`

`=20 . [ 33 : 11 - 2 ] - 9 . 2`

`=20 . [ 3-2] - 18`

`=20. 1 - 18`

`=20-18`

`=2

Answer 2

\(2^2.5\left[\left(5^2+2^3\right):11-2\right]-3^2.2\)

\(=4.5\left[\left(25+8\right):11-2\right]-9.2\)

\(=4.5\left(33:11-2\right)-18\)

\(=4.5\left(3-2\right)-18\)

\(=4.5.1-18\)

\(=2\)
