Explicación paso a paso:
a) √x - 25 = - 7
√x = - 7 + 25
x = 18²
x = 324
b) √x-14 - 8 = 9
√x-14 = 9 + 8
√x-14 = 17
x - 14 = 17²
x = 289 +14
x = 303
c) ∛19x+153 = 7
19x + 153 = 7³
19x = 343 - 153
x = 190 : 19
x = 10
d) 5. √x+6 - 8 = 12
5.√x+6 = 12 + 8
√x+6 = 20 : 5
x + 6 = 4 ²
x = 16 -6
e) 2.⁴√3x+4 + 1 = 9
2.⁴√3x+4 = 9 - 1
⁴√3x+4 = 8 : 2
3x+4 = 4⁴
3x = 256 - 4
x = 252 : 3
x = 84
f) 3 . (x + 1)² = 147
(x + 1)² = 147 : 3
x + 1 = √49
x = 7 - 1
x = 6
