Answer :
[tex]one \ half \to \frac{1}{2} \\\\ three \ tenths \to \frac{3}{10} \\\\ \frac{1}{2}^{(5}+\frac{3}{10}= \\\\=\frac{5+3}{10}= \\\\ =\frac{8}{10}\to\boxed{\boxed{\frac{4}{5}}}[/tex]
[tex]\boxed{ \frac{1}{2}+ \frac{3}{10} = \frac{1\times5}{2\times5} + \frac{3}{10} = \frac{5}{10}+ \frac{3}{10} = \frac{8}{10}=0,8 }[/tex]
