- 24.3
- 2.43
- 0.243
- 0.0243
Answer: Option D
1. \begin{aligned}
\sqrt{41 - \sqrt{21 + \sqrt{19 - \sqrt{9}}}}
\end{aligned}
- 4
- 26
- 16
- 6
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}
2. Evaluate
\begin{aligned}
\sqrt{248+\sqrt{64}}
\end{aligned}
- 14
- 26
- 16
- 36
Answer: Option C
Explanation:
\begin{aligned}
= \sqrt{248+\sqrt{64}}
\end{aligned}
\begin{aligned}
= \sqrt{248+8}
\end{aligned}
\begin{aligned}
= \sqrt{256}
\end{aligned}
\begin{aligned}
= 16
\end{aligned}
3. \begin{aligned} \sqrt{\frac{0.081 * 0.484 }{0.0064 * 6.25}} \end{aligned}
- 0.66
- 0.77
- 0.88
- 0.99
Answer: Option D
4. Evaluate \begin{aligned}
\sqrt{1471369}
\end{aligned}
- 1213
- 1223
- 1233
- 1243
Answer: Option A
5. Evaluate
\begin{aligned}
\sqrt{10+\sqrt{25+\sqrt{108+\sqrt{154+\sqrt{225}}}}}
\end{aligned}
- 16
- 8
- 6
- 4
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}
