When coping with radical expressions, we apply the technique of rationalisation. Suppose we will ‘rationalise’ the denominator to convert the denominator into a rational number.
Rationalizing the denominator means eliminating the unconventional expressions in the denominator in order that we wouldn’t have square roots, cubic roots, or any other roots. The major thought in rationalizing denominators is to multiply the original fraction by an acceptable worth in order that after simplifying, the denominator now not incorporates radicals. Differentiated practice overlaying simplifying radicals and rationalizing denominators.
Instance Questions
This multiplication made the radical phrases cancel out, which is exactly what I need. This “identical numbers but the opposite signal in the center” thing is the “conjugate” of the unique expression.
This last type, “five, root-three, divided by three”, is the “proper” answer they’re on the lookout for. Thus, by multiplying 1/√3 by √3/√3 we are ready to get the required equivalent expression.
