Question

solve the equation radical x equals 11

Answer 1

This equation?

\(\sqrt{x} = 11\)

Answer 2

You are allowed to add the same number to both sides of an equation.
You are also allowed to multiply both saides of an equation by the same number.

Similarly, you are allowed to square both sides of an equation, but when you find solutions, then you must check all solutions in the original equation to make sure they work.

Answer 3

Square both sides.
What do you get?

Answer 4

yes i got 121?

Answer 5

When you square BOTH sides you get
x = 121
Now check 121 for x in the original equation. If it works, then that is the solution.
