Find the value of x
$$\begin{aligned} \frac{2707}{\sqrt{x}} = 27.07 \end{aligned}$$

Answer: Option B

Answer: Option B

Explanation:

$$\begin{aligned} => \sqrt{81} + \sqrt{0.81} = 10.09 - X \end{aligned}$$

$$\begin{aligned} => 9 + 0.9 = 10.09 - X \end{aligned}$$

$$\begin{aligned} => X = 10.09 - 9.9 = 0.19 \end{aligned}$$

Answer: Option C

Explanation:

21*21*21 = 9261

Answer: Option D

Explanation:

$$\begin{aligned} = \sqrt{41 - \sqrt{21 + \sqrt{19 - 3}}} \end{aligned}$$

$$\begin{aligned} = \sqrt{41 - \sqrt{21 + \sqrt{16}}} \end{aligned}$$

$$\begin{aligned} = \sqrt{41 - \sqrt{21 + 4}} \end{aligned}$$

$$\begin{aligned} = \sqrt{41 - \sqrt{25}} \end{aligned}$$

$$\begin{aligned} = \sqrt{41 - \sqrt{25}} \end{aligned}$$

$$\begin{aligned} = \sqrt{41 - 5} \end{aligned}$$

$$\begin{aligned} = \sqrt{36} = 6 \end{aligned}$$

Answer: Option D

Explanation:

$$\begin{aligned} = \sqrt{10+\sqrt{25+\sqrt{108+\sqrt{154+\sqrt{225}}}}} \end{aligned}$$

$$\begin{aligned} =\sqrt{10+\sqrt{25+\sqrt{108+\sqrt{154+15}}}} \end{aligned}$$

$$\begin{aligned} =\sqrt{10+\sqrt{25+\sqrt{108+\sqrt{154+15}}}} \end{aligned}$$

$$\begin{aligned} =\sqrt{10+\sqrt{25+\sqrt{108+\sqrt{169}}}} \end{aligned}$$

$$\begin{aligned} =\sqrt{10+\sqrt{25+\sqrt{108+13}}} \end{aligned}$$

$$\begin{aligned} =\sqrt{10+\sqrt{25+\sqrt{121}}} \end{aligned}$$

$$\begin{aligned} =\sqrt{10+\sqrt{25+11}} \end{aligned}$$

$$\begin{aligned} =\sqrt{10+\sqrt{36}} \end{aligned}$$

$$\begin{aligned} =\sqrt{10+6} \end{aligned}$$

$$\begin{aligned} =\sqrt{16} = 4 \end{aligned}$$
