If `3-2 ` means `3 ^(2) xx 2 ^(2) and (8 +2)` means `8^(2) div 2 ^(4),` then te value of `5 - ( 9 + 3)` is

A

`(-5)/(12)`

B

`25`

C

`5`

D

`- 60`

Text Solution

Verified by Experts

The correct Answer is:
D
Using the symbols correctly as given in the question, we get
`5 - ( 9 +3) = 5 ^(2) xx ( 9 + 3) ^(2)`
`= 5 ^(2) xx ( 9 ^(2) div 3 ^(4)) ^( 3)`
`= 25 xx (18 div 81) ^(3)`
`= 25 xx 1 = 25`
Therefore, the value of the given expression = 25.
