Given the numerical equation:

(½)^2 + (⅔)^2

Solution:

Square first the two equations before adding.

= (½)^2 + (⅔)^2

= ¼ + 4/9

=0.25 + 0.44444…

=0.694444…

The answer is a repeating decimal, hence we can equate it either with a repeating word enclosed with a parenthesis, a dash line, or an ellipsis. In our case, we will use the ellipsis.

Final answer: 

=0.694444…
