7. Solve the following equation.
a. 42x . 8x - 1 = 32
b. 1253x / 5x + 4 = 25x - 2 / 3125
Jawaban :
a. 42x . 8x - 1 = 32
24x . 23(x - 1) = 25
4x + 3x - 3 = 5
7x =8
x = 8/7
b. 1253x / 5x + 4 = 25x - 2 / 3125
1253x . 3125 = 25x - 2 . 5x + 4
59x . 55 = 52(x - 2) . 5x + 4
9x + 5 = 2x - 4 + x + 4
9x + 5 = 3x
6x = -5
x = -5/6
