MCQ
Given that, $\sqrt{33964}=58$, the value of $\sqrt{3364}+\sqrt{33\cdot64}$ is:
- A$60$
- B$53.8$
- C$63.4$
- ✓$63.8$
✓
Answer
Correct option: D.
$63.8$
From question, $\sqrt{3365}=58$
Now, $\sqrt{3364}+\sqrt{33\cdot64}=58+\sqrt{3364\times10^-2}=58+58\times10^-1$
$= 58 + 5.8 = 63.8$
Now, $\sqrt{3364}+\sqrt{33\cdot64}=58+\sqrt{3364\times10^-2}=58+58\times10^-1$
$= 58 + 5.8 = 63.8$
