If a is a positive real no. then `(i)|x|lta (ii)|x|>a`

If a is a positive real no.then (i)|x|

If x and y are positive real number, then :

Property 2(i) (Modulus function) If a and b are positive real no's then (1) x^(2) =a^(2)(3)x^(2) a^(2)

If r is a positive real no. and a be a fixed real no. then find the range of x in (i) |x-a|ltr(ii)|x-a|ler(iii)|x-a|gtr(iv) |x-a|ger

If x is a positive real number, then the greatest value of (7-x)(x+5)^(2) , is

If |x|< a where a is positive real number then,

Let a;b be positive real no.;a<|x|

If x,yand z are positive real numbers,then the minimum value of (x)/(y)+(y)/(z)+(z)/(x) is:

State which of the following sets are finite and which infinite : (i) {x:x is a positive integral root of x^(2)-2x-15=0} (ii) {x:x is human being in the world} (iii) {x:x is a multiple of 3} (iv) {x:x is a real number between a and 2}.
