If a is rational and b is irrational, show that :
a+b

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.

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

(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 x is a rational number and y is an irrational number, then (a) both x + y a n d x y are necessarily rational (b) both x + y a n d x y are necessarily irrational (c) x y is necessarily irrational, but x + y can be either rational or irrational (d) x + y is necessarily irrational, but x y can be either rational or irrational
