$\bf{\text{Solution Outline:}}$ To simplify the given expression, $(2-3i)+(6+8i) ,$ remove the grouping symbols. Then combine the real parts and the imaginary parts. $\bf{\text{Solution Details:}}$ Removing the grouping symbols, the given expression is equivalent to \begin{array}{l}\require{cancel} 2-3i+6+8i .\end{array} Combining the real parts and the imaginary parts results to \begin{array}{l}\require{cancel} (2+6)+(-3i+8i) \\\\= 8+5i .\end{array}
