MCQ
$(125)^{-\frac{1}{3}}=?$
- A$5$
- B$-5$
- ✓$\frac{1}{5}$
- D$-\frac{1}{5}$
✓
Answer
Correct option: C.
$\frac{1}{5}$
$(125)^{-\frac{1}{3}}=\frac{1}{(125)^{\frac{1}{3}}}$
$=\frac{1}{5^{3-\frac{1}{3}}}=\frac{1}{5}$
Hence, the correct answer is option $(c).$
$=\frac{1}{5^{3-\frac{1}{3}}}=\frac{1}{5}$
Hence, the correct answer is option $(c).$
