Answer 1

$( { \frac{2}{3} )}^{5} \times ( {2}^{5} )^{3} \times {3}^{7} \div ( { {2}^{10} \times 3})^{2} = 1 \\ {2}^{5} \times {3}^{ - 5} \times {2}^{15} \times {3}^{7} \times {2}^{ - 20} \times {3}^{ - 2} = 1 \\ {2}^{5 + 15 - 20} \times {3}^{ - 5 + 7 - 2} = 1 \\ {2}^{0} \times {3}^{0} = 1 \\ 1 \times 1 = 1 \\ 1 = 1$
