Question

find the multiplicative inverse of -1/2. also, verify that -(-x) =x if x = -1/2​

Answer 1

Step-by-step explanation:

multiplicative inverse of -1/2:-

(-1/2)^-1= -2

so,multiplicative inverse of -1/2 is -2

-(-x)=x with x= (-1/2)

0-(-1/2)

{0-(-1)}/2

0+1/2

1/2

hence ,prove that -(-x) =x with x = -1/2
