Rationalisation of A Monomial Square Root and Cube Root
For the fundamental technique, the numerator and denominator must be multiplied by the same factor.
Example 1:
To rationalise this kind of monomial, bring in the factor :
The square root disappears from the denominator, because it is squared:
This gives the result, after simplification:
Example 2:
To rationalise this radical, bring in the factor :
The cube root disappears from the denominator, because it is cubed:
This gives the result, after simplification:
