Answer 1

Respuesta:

a) x² = 81

x = √81

x = 9

b) √x = 2

x = 2²

x = 4

c) x² - 1 = 8

x² = 8+1

x = √9

x = 3

d) x⁴ ÷ 8 + 1 = 33

x⁴ ÷ 8 = 33-1

x⁴ = 32×8

x = ⁴√256

x = 4

e) (x+1)² = 196

x+1 = √196

x = 14-1

x = 13

f) 3x² - 15 = 33

3x² = 33 + 15

x² = 48/3

x = √16

x = 4

g) √x - 3 = 4

√x = 4+3

x = 7²

x = 49

h) 3 ⁴√x = 6

⁴√x = 6/3

x = 2⁴

x = 16

i) √(x+2) = 3

x+2 = 3²

x = 9 - 2

x = 7

j) ³√(x+4) - 1 = 4

³√(x+4) = 4+1

x+4 = 5³

x = 125-4

x = 121
