Solve the following radical equation.121−z⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯√−z=11

The equation you provided seems to be incomplete or incorrectly formatted. However, if you're trying to solve a radical equation such as √(121 - z) = 11, here are the steps:

Step 1: Square both sides of the equation to eliminate the square root. (√(121 - z))^2 = 11^2 This simplifies to: 121 - z = 121

Step 2: Solve for z. Subtract 121 from both sides:

• z = 0

Multiply both sides by -1 to solve for z: z = 0

So, the solution to the equation √(121 - z) = 11 is z = 0.
