MCQ
If a = 3 and b = 2 , then $(3 a-4 b)^{b-a} \div(4 a-3 b)^{2 b-a}$ is equal to
- A1
- B6
- ✓$1 / 6$
- D$2 / 3$
✓
Answer
Correct option: C.
$1 / 6$
(c)
For a = 3 and b = 2 we find that
$(3 a-4 b)^{b-a} \div(4 a-3 b)^{2 b-a}=(9-8)^{-1} \div(12-6)^1=(1)^{-1} \div(6)^1=1 \div 6=\frac{1}{6}$
For a = 3 and b = 2 we find that
$(3 a-4 b)^{b-a} \div(4 a-3 b)^{2 b-a}=(9-8)^{-1} \div(12-6)^1=(1)^{-1} \div(6)^1=1 \div 6=\frac{1}{6}$
