Answer 1

$\frac{(14 {a}^{5} {b}^{7})^{3} }{ {7}^{2} {a}^{14} {b}^{20} } = \frac{{14}^{3} {a}^{15} {b}^{21} }{{7}^{2} {a}^{14} {b}^{20} } = \frac{2744ab}{49} = 56ab \\ \frac{ { ({21}^{3} \times {5}^{2}) }^{2} }{ {7}^{5} \times {5}^{3} \times {3}^{6} } = \frac{ {21}^{6} \times {5}^{4} }{{7}^{5} \times {5}^{3} \times {3}^{6}} = 7 \times 5 = 35$
