Answer 2

Answer:

Concept: rationalization of the given fraction.

Given: if $\sqrt{2} =1.4142$

To find: so find $\frac{\sqrt{2}-1}{\sqrt{2} +1}$

Step-by-step explanation:

In the rationalization process , the given numerator and denominator both is being multiplied by the number of opposite sign of that of the denominator.

and when two roots is multiplied , the root removes and the number itself remains.

so, $\frac{\sqrt{2}-1}{\sqrt{2} +1}$

or, $\frac{\sqrt{2}-1}{\sqrt{2} +1}*\frac{\sqrt{2}-1}{\sqrt{2} -1}$

or, $\frac{(\sqrt{2}-1) ^{2} }{2-1}$

or, $\frac{\sqrt{2}-1 }{1}$

or, when $\sqrt{2} =1.4142$

the answer is $0.4142$.
