ANSWER:

{ \huge{ \red{given : }}} \\ \\ \sf{m = 2 \: and \: n \: = 3} \\ \\ { \huge{ \blue{solution : }}} \\ \\ \sf{(i) \: {4m}^{2} - 302} \\ \rightarrow \sf{4 {(2)}^{2} - 302} \\ \rightarrow \sf{16 - 302} \\ \rightarrow{ \boxed{ \sf{ - 286}}} \\ \\ \\ \sf{(ii) \: {4m}^{2} - {3n}^{2} } \\ \rightarrow \sf{4 {(2)}^{2} - 3 {(3)}^{2} } \\ \rightarrow \sf{4 ( 4) - 3 ( 9)} \\ \rightarrow \sf{16 - 27} \\ \rightarrow{ \boxed{ \sf{ - 11}}}
