Vedclass · Answer

(D) To evaluate $\frac{\sqrt{2}}{2+\sqrt{2}}$,we first rationalize the denominator by multiplying the numerator and the denominator by the conjugate $(2-\sqrt{2})$:$\frac{\sqrt{2}}{2+\sqrt{2}} 	imes \frac{2-\sqrt{2}}{2-\sqrt{2}} = \frac{2\sqrt{2} - (\sqrt{2})^2}{2^2 - (\sqrt{2})^2}$$= \frac{2\sqrt{2} - 2}{4 - 2} = \frac{2(\sqrt{2} - 1)}{2} = \sqrt{2} - 1$Given $\sqrt{2} = 1.414$,we substitute this value:$1.414 - 1 = 0.414$Thus,the correct value is $0.414$.
