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.
