Question : If $a = 64$ and $b = 289$, then the value of $\sqrt{\sqrt{\sqrt{a}+\sqrt{b}}-\sqrt{\sqrt{b}-\sqrt{a}}}$ is:
Option 1: $2^{\frac{1}{2}}$
Option 2: $2$
Option 3: $4$
Option 4: $–1$
Correct Answer: $2^{\frac{1}{2}}$
Solution : Given: $a = 64$ and $b = 289$ The given expression is $\sqrt{\sqrt{\sqrt{a}+\sqrt{b}}-\sqrt{\sqrt{b}-\sqrt{a}}}$. Substitute the value of $a = 64$ and $b = 289$ in the above equation, we get, $=\sqrt{\sqrt{\sqrt{64}+\sqrt{289}}-\sqrt{\sqrt{289} - \sqrt{64}}}$ $=\sqrt{\sqrt{8+17}-\sqrt{17-8}}$ $=\sqrt{\sqrt{25}-\sqrt{9}}$ $=\sqrt{5-3}$ $=2^{\frac{1}{2}}$ Hence, the correct answer is $2^{\frac{1}{2}}$.
Question : Directions: From the given alternative words, select the word that cannot be formed using the letters of the given word. HARBINGER
Option 1: BARRING
Option 2: GARNER
Option 3: GARBAGE
Option 4: RANGER
Correct Answer: GARBAGE
Solution : Given: HARBINGER
Now, let's compare all the option words with the word HARBINGER – First option: BARRING; All the letters of BARRING are present in the word HARBINGER. Second option: GARNER; All the letters of GARNER are present in the word HARBINGER. Third option: GARBAGE;
Question : The value of $\frac{4 \tan ^2 30^{\circ}+\sin ^2 30^{\circ} \cos ^2 45^{\circ}+\sec ^2 48^{\circ}-\cot ^2 42^{\circ}}{\cos 37^{\circ} \sin 53^{\circ}+\sin 37^{\circ} \cos 53^{\circ}+\tan 18^{\circ} \tan 72^{\circ}}$ is:
Option 1: $\frac{35}{48}$
Option 2: $\frac{59}{48}$
Option 3: $\frac{49}{24}$
Option 4: $\frac{35}{24}$
Correct Answer: $\frac{59}{48}$
Solution : Given: $\frac{4 \tan ^2 30^{\circ}+\sin ^2 30^{\circ} \cos ^2 45^{\circ}+\sec ^2 48^{\circ}-\cot ^2 42^{\circ}}{\cos 37^{\circ} \sin 53^{\circ}+\sin 37^{\circ} \cos 53^{\circ}+\tan 18^{\circ} \tan 72^{\circ}}$ We know that $\tan 30^{\circ} = \frac{1}{\sqrt{3}}$ $\sin 30^{\circ} = \frac{1}{2}$ $\cos 45^{\circ} = \frac{1}{\sqrt{2}}$ $\cos 37^{\circ} = \cos (90^{\circ} - 53^{\circ})
