Answer 1

${2}^{9} \times {4}^{2} \times {5}^{3 } \div 16 \times {10}^{2 } \\ = {2}^{9} \times {2}^{4} \times {5}^{3 } \div {2}^{4} \times {5}^{2} \times {2 }^{2} \\ = {2}^{9 - 2} \times {2}^{3 - 2} \\ = {2}^{7 } \times {5}^{1} \\ = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 5 \\ = 640$
