Doing this you must follow the pemdas method which is 

 

P - Parenthasses

E - Exponets

M/D - Multiplication/division  

A/S - Addition and sutraction  

 

 

So, were given the equation \(2 + {3}^{2} - (3 - 1)\) 

 

 

So in pemdas it first states we must do the parenthasses so will start with subtracting 1 from 3 ( 3 - 1) = 2 

 

 

 

Our equation now is \(2 + {3}^{2} - 2\) 

 

Next step in pemdas is do the exponets and there are exponets so we can take care of that 3² Is 3 * 3 = 9 

 

 

So we can add that to our equation \(2 + 9 * 2\)

 

 

Now we know that multilcation is the next step in the pemdas process so we need to multiply 9 times 2 and 9 * 2 = 18 

 

and all that's left is \(2 + 18\)

 

 

And 2 + 18 = 20 

 

 

So, the value to the expression is 20
