Question

I want the answer of
"Find the R.F. Of 7√2"

Answer 1

Answer:

Step-by-step explanation:

$\frac{1}{7\sqrt{2} } \ = \ \frac{1}{7\sqrt{2} } \ * \ \frac{\sqrt{2} }{\sqrt{2} }$

$\frac{1 \ * \ \sqrt{2} }{7\sqrt{2} \ * \ \sqrt{2} } \ = \ \frac{\sqrt{2} }{7 * 2} \ = \ \frac{\sqrt{2} }{ 14}$

Therefore the R.F. of  7√2 is √2 which is the numerator
