Answer 1

$a)1.7 {a}^{ - 7} {b}^{14} \times 5.4 {a}^{ - 10} {b}^{ - 8} = \frac{1.7 {b}^{14} \times 5.4}{ {a}^{17} {b}^{8} } = \frac{9.18 {b}^{6} }{ {a}^{17} }$
$b) (\frac{5 {x}^{3} }{3 {y}^{2} } ) ^{ - 2} \times 100 {x}^{12} {y}^{ - 6} = \frac{9 {y}^{4} \times 100 {x}^{12} }{25 {x}^{6} {y}^{6} } = \frac{36 {x}^{6} }{ {y}^{2} }$
