Solving Square and Cube Root Equations

Solve for x; identify extraneous solutions (if any).

• x = 17

• x = 5

• x = 3

• no solution; x = 5 is extraneous

Solve for x; identify extraneous solutions (if any).

• x = 3; x = - 1 is extraneous

• x = - 1; x = 3 is extraneous

• x = 3; x = - 1

• no solution; x = 3 and x = - 1 are extraneous
