16a4 b5. 14c2 x6. 7c3​

Answer 1

$\frac{ {21c}^{3} {x}^{5} }{ {16a}^{4} {b}^{5} } \times \frac{ {8a}^{3} {b}^{3} }{ {14c}^{2} {x}^{6} } \times \frac{3 {a}^{3} {b}^{2} }{ {7c}^{3} } = \frac{3c}{2a {b}^{2} } \times \frac{1}{2x} \times \frac{ {3a}^{3} {b}^{2} }{ {7c}^{3} } = \frac{3}{2} \times \frac{1}{2x} \times \frac{3 {a}^{2} }{ {7c}^{2} } = \frac{9 {a}^{2} }{28 {xc}^{2} }$
