If `A&B` are two ratinal numbers and `A B ,A+Ba n dA-B` are rational numbers, then `A//B` is: a. always rational b. never rational c. rational when `B!=0` d. rational when `A!=0`

If A&B are two ratinal numbers and AB,A+B and A-B are rational numbers, then A/B is: a.always rational b.never rational c.rational when B!=0 d.rational when A!=0

If A & B are two rational numbers and AB, A + B and A -B are rational numbers, then A/B is :

If A and B represent a rational number,then (A-B) is equal to

There are ________ rational numbers between any two rational numbers.

Find rational number between a and b .

(d) (0)/(0) is a rational number.

If in DeltaABC, angle A=90^(@) and c, sin B cos B are rational numbers, then show a and b are rational .

if (log)_a x=b for permissible values of a and x then identify the statements which can be correct. (a) If a and b are two irrational numbers then x can be rational (b) if a is rational and b is irrational, then x can be rational (c) if a is irrational and b is rational, then x can be rational (d) If a and b are two rational numbers then x can be rational .

If (log)_a x=b for permissible values of a and x , then identify the statement(s) which can be correct. (a)If a and b are two irrational numbers, then x can be rational. (b)If a is rational and b is irrational, then x can be rational. (c)If a is irrational and b is rational, then x can be rational. (d)if aa n d b are rational, then x can be rational.
