Step-by-step explanation:

by \: law \:  ({a}^{m}  \div  {a}^{n} =  {a}^{m - n}  ) \\ solving \: the \: brackets \\  ({5}^{21}  \div  {5}^{16} ) =  {5}^{21 - 16}  =  {5}^{5}  \\ moving \: onto \: the \: sum \\  {5}^{5}  \times  {5}^{10}  \\  {5}^{5 + 10} (by \: law \:  {a}^{m}  \times  {a}^{n}  =  {a}^{m +n } ) \\  =  {5}^{15}  \\  = 30517578125</p><p>
