Exercise 32 Question 1 Rationalise the denominator of each of the following (ivii) (i) (ii) (iii) (iv) (v) (vi) (vii) Answer (i) As there is √5 in the denominator and we know that √5 x √5 = 5 So, multiply numerator and denominator by √5,.

Rationalise the denominator 3+122 3. The lowest rationalizing factor of 3 5 2 3 is 3 5 − m 3 The value of m is Medium View solution > View more. How do you rationalise the denominator 1/√32?. After substitution (√3)²2(√3)(2)2²−(√7)² simplifies to (34√34)−7 → 4√3 So the expression after rationalizing the denominator once is (√21−2√7−1)/(4√3) But we’re not done yet There is still the radical √3 remaining in the denominator So we have to rationalize it a second time, albeit this time is much.

 To rationalise the denominator of 1/(√5 √3 √2) we have to multiply its numerator and denominator with its conjugate, which we consider to be (√5 – (√3 √2)) 1/(√5 √3 √2) = 1/(√5 (√3 √2)) x (√5 (√3 √2)) / (√5 (√3 √2)). * 1 point 19 25 NONE OF THESE. Let us learn the technique to rationalize the following fraction $$\frac{\sqrt{7}}{2\sqrt{7}}$$ Step1 Examine the fraction – The denominator of the above fraction has a binomial radical ie, is the sum of two terms, one of which is an irrational number Step2 Multiply the numerator and denominator of the fraction with the conjugate of the radical.

The rationalizing factor of 2√3 is √3 2√3 × √3 = 2 × 3 = 6 Rationalize the Denominator Meaning Rationalizing the denominator means the process of moving a root, for instance, a cube root or a square root from the bottom of a fraction (denominator) to the top of.

B, which can be useful when rationalizing a denominator or numerator For example, 2− √ 43−x and 2 √ 43−x are conjugate expressions Example Rationalize the denominator in the expression √ x y √ x−2 √ y To rationalize the denominator, we multiply both the numerator and denominator by the conjugate of the denominator √ x. Rationalising means to convert a surd (= an irrational number) into a rational number by multiplication with a suitable surd to convert the former into a rational number In the present case if we multiply the numerator and denominator of the given expression by √3 we get (√5) (√3)/2√3 (√3) = √15/2 (3) = √15/6.  Step 1 Multiply numerator and denominator by a radical that will get rid of the radical in the denominator If the radical in the denominator is a square root, then you multiply by a square root that will give you a perfect square under the radical when multiplied by the denominator If the radical in the denominator is a cube root, then you multiply by a cube root.

Rationalising means to convert a surd (= an irrational number) into a rational number by multiplication with a suitable surd to convert the former into a rational number In the present case if we multiply the numerator and denominator of the given expression by √3 we get (√5) (√3)/2√3 (√3) = √15/2 (3) = √15/6. SolutionShow Solution `1/ √3 √2 1` = `1/ (√3 √2) 1 xx (√3 √2) 1/ (√3 √2) 1` = ` (√3 √2 1)/ (√3 √2)^2 (1)^2` = ` (√3 √2 1)/ (√3)^2 2√6 (√2)^2 1 ` = ` (√3 √2 1)/ (3 2√6 2 1)` = ` (√3 √2 1)/ ( 4 2√6 )` = ` (√3 √2) 1/ 2 ( 2 √6 )`.
