A) \[2-\sqrt{4}\]
B) \[{{(\sqrt{5})}^{2}}\]
C) \[\sqrt{9}-\sqrt{4}\]
D) \[\sqrt{2}-\sqrt{3}\]
Correct Answer: D
Solution :
\[\Rightarrow \] (Rational number) \[L.C.M.=\frac{140\times 605}{11}=7700\](Rational number) \[\text{1}00\text{1}=\text{91}\times \text{1}0+\text{91}\] (Rational number) Also, the sum or difference of two irrational numbers is irrational. Thus, \[\text{91}0=\text{91}\times \text{1}0+0\]is irrational.
