Question : If $(\sqrt 3 +1)^{2}=x+\sqrt 3 y$, then the value of $(x+y)$ is:
Option 1: 2
Option 2: 4
Option 3: 6
Option 4: 8
Correct Answer: 6
Solution : Given: $(\sqrt{3}+1)^2 = x+\sqrt{3}y$ ⇒ $(3+1+2\sqrt{3})=x+\sqrt{3}y$ ⇒ $(4+2\sqrt{3})=x+\sqrt{3}y$ Comparing both sides, we get $x=4$ and $y =2$. Thus, $(x+y)=(4+2)=6$ Hence, the correct answer is 6.
Question : If $3^{10} × 27^{2}= 9^{2}×3^{n}$, then the value of $n$ is:
Option 1: 10
Option 2: 12
Option 3: 15
Option 4: 30
Correct Answer: 12
Solution : Given: $3^{10} × 27^{2}= 9^{2}×3^{n}$ Simplify the given expression for the same base, $⇒3^{10} × (3^{3})^{2}= 9^{2}×3^{n}$ $⇒(3^{10+6})= (3^{2})^{2}×3^{n}$ $⇒3^{16}= 3^{4}×3^{n}$ $⇒3^{16}= 3^{4+n}$ By comparing this, $⇒16=4+n$ $\therefore n =12$ Hence, the correct answer is 12.
