Question

 

Answer 1

`2.[(7-3^3:3^2):2^2+99]-100`

`= 2.[(7-3):4+99]-100`

`= 2.(4:4+99)-100`

`= 2.(1+99)-100`

`=2.100-100`

`=200-100`

`=100`

Answer 2

2 . [ ( 7 − 3 3 : 3 2 ) : 2 2 + 99 ] − 100 = 2 . [ ( 7 − 3 ) : 4 + 99 ] − 100 = 2 . ( 4 : 4 + 99 ) − 100 = 2 . ( 1 + 99 ) − 100 = 2.100 − 100 = 200 − 100 = 100
