d) 3. &x = 6
f) √x+2=3
h) x 4 - 1 = 4

ayuda pls ​

Answer 1

Respuesta:

a) x^2 - 1 = 8

x^2 = 8 + 1

x^2 = 9

x = √9

x = 3

c) x : 8 + 1 = 33

x : 8 = 33 - 1

x : 8 = 32

x = 32 . 8

x = 236

e) 2x + 1 = 55

2x = 55 - 1

2x = 54

x = 54 : 2

x = 27

g) (x + 1) = 64

x + 1 = 64

x = 64 - 1

x = 63

b) √x - 3 = 4

√x = 4 + 3

√x = 7

x = 7^2

x = 49

d) 3 . 8x = 6

8x = 6/3

8x = 2

x = 2/8

x = 0.25

f) √x + 2 = 3

√x = 3 - 2

√x = 1

x = 1^2

x = 1

h) x4 - 1 = 4

x4 = 4 + 1

x4 = 5

x = 5/4

x = 1.25
