My honorab...We will follow a similar process to rationalize higher roots. To rationalize a denominator with a higher index radical, we multiply the numerator and denominator by a radical that would give us a radicand that is a perfect power of the index. When we simplify the new radical, the denominator will no longer have a radical. For example, Figure 8.5.14We must always multiply numerator and denominator with the cube root of the square of the term in the denominator to rationalise. We can rationalize negative cubic root also by the same way. Similarly, we can rationalize. 2 7–√3 2 7 3. Here a=2 and b=7.
