Bài 2: Tìm x, biết:
a) \(\frac{x}{-18} = \frac{-8}{12}\)
b) \(\frac{37 - x}{x + 13} = \frac{3}{7}\)
c) \(2x\left(x - \frac{2}{3}\right) = 0\)
d) \(\left(x + \frac{1}{2}\right)^2 = \frac{1}{16}\)
e) \((x + 5)^3 = -64\)
f) \((5x + 1)^2 = \frac{36}{49}\)
g) \(2x^2 + 2x^4 = 544\)
h) \(3^{(x - 2)(x - 3)} = 1\)
i) \((4x - 1)^{30} = (4x - 1)\)
Bài 3: Tìm x, biết:
a) \(|x - 5| = 8\)
b) \(-\frac{2}{3} |x - 4| - \frac{5}{2} = 0\)
c) \(|9 - 7x| + 7 = 26\)
d) \(3 \cdot |x - \frac{1}{2}| - 4 = 7\)
e) \(|2 - \frac{3}{2}|x| - 4 = -x + 2\)
