Which of the two values 10^ (-2) and 10^ (-3), is x more close to?
(1) x is more close to 10^ (-4) than to 10^(-1).
(2) x is more close to 10^ (-3) than to 10^ (-1).

(1) x is more close to 10^ (-4) than to 10^(-1).
(2) x is more close to 10^ (-3) than to 10^ (-1).
MID VALUE OF 10^ (-2) and 10^ (-3)= 0.0055
1) MID VALUE OF 10^ (-4) and 10^(-1)= 0.05005
hence x< 0.05
also 0.01< 0.05
WE CANT ACTUALLY COMMENT ON value of x relative to 0.0055

hence INSUFFICIENT

2) MID VALUE OF 10^ (-3) AND 10^ (-1)= 0.0505
HENCE x< 0.0505
again 0.01<0.05

AGAIN, WE CANT ACTUALLY COMMENT ON value of x relative to 0.0055

HENCE INSUFFICIENT

1+2

AGAIN ITS THE SAME SITUATION x< 0.0505 AND 0.01<0.05
WE CANT JUST COMMENT ANYTHING REGARDING x RELATIVE TO 0.0055

INSUFFICIENT

HENCE E.
