• x ≥ 16

• x ≤ 16

• x < 4
• x > 5
• x = 4
• x > 4

Solve the following radical inequality algebraically: √(5x - 4) > 6

• x > 16 or x < -20

• x > 10 or x < -14

• x > 20 or x < -16

• x > 16 or x < -20

If you square both sides of a radical equation and obtain a solution that does not satisfy the original equation, you have found what?

• nth root
• extraneous solution
• radical equation 
• identity function
