Answer and Step-by-step explanation:
I'm a little confused by the question since I don't exactly know where the exponent "-2" is supposed to be so :
If you meant your questions to be like this : [tex](\frac{1^-^2}{2})+12[/tex]
Then the answer for it is :
[tex]=\frac{1^-^2}{2} +12[/tex]
[tex]=\frac{25}{2}[/tex]
But If you meant your questions to be like this : [tex](\frac{1}{2^-^2} )+12[/tex]
The the answer for it is :
[tex]=\frac{1}{2^-^2} +12[/tex]
[tex]=16[/tex]
