Answer 1

1.  x^4 = 16
     x    = (16)^(1/4)
     x    = (2^4)^(1/4)
     x   = 2

2. (x²)³ = 64
     x^6 = 64
     x  = (64)^(1/6)
     x  = (2^6)^(1/6)
     x  = 2

3. 2x³ + 1 = 17
    2x³ = 16
      x³ = 8
      x = ∛8
      x = 2

4.  3√x + 4 = 19
     3√x = 15
       √x = 5
         x = 5²
         x = 25

5. (2x+3)² = 81
    2x + 3 = √81
    2x + 3 = 9
    2x = 6
      x = 3

6. √5x - 4 = 9
     √5 x = 5
         x = 5 / √5
         x = √5

7. 5  (x-2)³ = 135
    (x-2)³ = 27
    (x-2) = ∛27
     x - 2 = 3
        x = 5

8. 4*∛x + 7 = 24
    4∛x+7= 6
      x+7= 6³
      x  = 216 - 7
      x = 209
