1.	5. 18 (25)= 4, find the values of :(x-1/x)
Answer» Step-by-step explanation:x= -18/ -25 x= 18/25 now mod (-x) = mod (-18/25)= 18/25 (as you take absolute value with mod i.e MULTIPLY any negative no. with -1 and any POSITIVE no. with +1) and mod (x) = mod (18/25) = 18/25 thus mod (x) = mod (-x) Note- mod of any number 'a' is represented as IaI
