Question

Verify that |-x|=|x|for the following values of x =-18/-25

Answer 1

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

Hope this helps....
