$\LARGE{} \sqrt[4]{256} \times \sqrt{25 - 16} \\ \\ \LARGE{} \sqrt[4]{ {4}^{4} } \\ \\ \LARGE{} \sqrt[\cancel{4}]{ {4}^{\cancel{4}} } \\ \\ \LARGE{}4 \\ \\ \LARGE{}4 \sqrt{25 - 16} \\ \\ \LARGE{}4 \sqrt{9} \\ \\ \LARGE{} \sqrt{ {3}^{2} } \\ \LARGE{}3 \\ \\ \LARGE{}4 \times 3 \\ \\ {\large\boxed{\boxed{  { \red{\large \tt 12 }}}}}$
