MCQ
$\frac{5^7}{6^7}$ will give the value:
- ✓$(\frac{5}{6})^7$
- B$(\frac{5}{6})^0$
- C$(\frac{5}{6})^{-7}$
- D$(\frac{6}{5})^{-7}$
✓
Answer
Correct option: A.
$(\frac{5}{6})^7$
By exponent law,
$\frac{\text{a}^\text{m}}{\text{b}^\text{m}}= \big(\frac{\text{a}}{\text{b}}\big)^\text{m}$
$\frac{5^7}{6^7} = \big(\frac{5}{7}\big)^7$
$\frac{\text{a}^\text{m}}{\text{b}^\text{m}}= \big(\frac{\text{a}}{\text{b}}\big)^\text{m}$
$\frac{5^7}{6^7} = \big(\frac{5}{7}\big)^7$
