Okay. Thank you for the clarification.

So to solve the equation \(\sqrt{12-\!\sqrt{12-\!\sqrt{12-\cdots}}}\) we will use the following equation:

n(n-1)=12; with the answer to the infinite nested radical function (x) being equal to n-1.

So,

n(n-1)=12

n = 4

n-1=?

4-1=3

Thus, the solution is 3.

Hope that answered your question!

Also, just a tip, don't place your questions in the header. It makes it a bit difficult to know the question that you are asking. You are supposed to place your question where you said "help please." Just switch the places, and you'll be perfectly fine!
