MCQ
The value of $\sqrt[4]{(64)^{-2}}$ is:
- A$\frac{1}{16}$
- B$\frac{1}{4}$
- ✓$\frac{1}{8}$
- D$\frac{1}{2}$
✓
Answer
Correct option: C.
$\frac{1}{8}$
$\sqrt[4]{(64)^{-2}}$
$\Rightarrow(64)^{\frac{-2}{4}}$
$\Rightarrow(64)^{\frac{-1}{2}}$ or $\frac{1}{\sqrt{64}}$
$\Rightarrow\frac{1}{8}$
$\Rightarrow(64)^{\frac{-2}{4}}$
$\Rightarrow(64)^{\frac{-1}{2}}$ or $\frac{1}{\sqrt{64}}$
$\Rightarrow\frac{1}{8}$
