Question

square root (x-12)^2=

Answer 1

√(x - 12)² = ±(x - 12) = | x - 12 |

Answer 2

With roots, you can write them two ways: the standard √(x-12), or you can also write it as (x-12)^(1/2). So in this case, since the number you have written down is the same as (x-12)^(2/2) it is the same as (x-12)^1. 

Answer 3

 

 

    √( X - 12 )² = X -1 2
