Do you know what is Rationalising??

anonymous · Answer

no

anonymous · Answer

Rationalising is done in case we have irrational denominator..

Rationalising means multiplying the numerator and denominator both by the same value so that the denominator contains no more irrational values or square root values or cube root values etc etc..
