If 92x frac 1 3 27x find x - WAEC Mathematics 2009 Question
If 92x = \(\frac{1}{3}\)(27x), find x
A
2
B
1
C
-1
D
-2
correct option: c
92x = \(\frac{1}{3}\)(27x)
(22)2x = \(\frac{(3^{3x})}{3}\)
(34x) = 33x - 1
4x = 3x - 1
4x - 3x = -1
x = -1
(22)2x = \(\frac{(3^{3x})}{3}\)
(34x) = 33x - 1
4x = 3x - 1
4x - 3x = -1
x = -1
