square root of x-1=3

So we square the three first ok i get it know thanks Chris

4-1=3 since x was 4 the square root of 4 is 2.did i do that right?

We have this zegroes:

√(x - 1) = 3

Let's square both sides........this gives........

x - 1 = 9

Add 1 to both sides

x = 10

And that's it.......

The answer is 10.
