Question

If √a,√b are surds such that √a×√b= x, where x is an integer, then
√a,√b are
a) conjugates to each other
b) R.F.'s to each other
c) equal surds
d) All the above​

Answer 1

a cojugates to each other

Answer 2

b is correct

Step-by-step explanation:

when root a + root b= integer both are conjugates of each other

when root a x root b =integer they are rationalising factors of each other

in the question they have multiplied the roots to get an integer this they are RF and we know every conjugate is an RF but vice versa may not be true

here we proved they r RF so we can't say that the RF is a conjugate
