If 5 div 8 means 5 xx sqrt8 and (4 +5) ...

If ` 5 div 8` means `5 xx sqrt8 and (4 +5)` means `4 ^(2) - 5,` then the value of `5 div (13 + 25)` is

A

`5 sqrt38`

B

`(5)/(12)`

C

`(5)/(38)`

D

`60`

Text Solution

Verified by Experts

The correct Answer is:
D
Using the symbols correctly as given in the question, we get
`(13 + 25) = 13 ^(2) - 25 = 169 - 25 = 144`
`5 div (13 + 25) = 5 div 144 = 5 xx sqrt144 = 5 xx 12 = 60`
Therefore, the value of the given expression = 60.
