Answer 1

Explicación paso a paso:

$a)2 {a}^{4} {b}^{5} - 18 {a}^{3} {b}^{10} \\ 2 ({a}^{4} {b}^{5} - 9 {a}^{3} {b}^{10}) \\2{a}^{3} (a{b}^{5} - 9{b}^{10} )\\2{a}^{3}{b}^{5}(a - 9 {b}^{5})$

$b)16{x}^{2}{y}^{7} - 8 {x}^{9} {y}^{6} + 20 {x}^{3} {y}^{8} \\ 4(4{x}^{2}{y}^{7} - 2 {x}^{9} {y}^{6} + 5 {x}^{3} {y}^{8}) \\ 4 {x}^{2} (4{y}^{7} - 2{x}^{7} {y}^{6} + 5 x {y}^{8}) \\ 4 {x}^{2} {y}^{6} (4y - 2{x}^{7} + 5 x {y}^{2})$

$c)24 {a}^{30} {b}^{60} {x}^{80} {y}^{90} + 6 {a}^{10} {x}^{40} \\ 6(4{a}^{30} {b}^{60} {x}^{80} {y}^{90} + {a}^{10} {x}^{40} ) \\ 6 {x}^{40} (4 {a}^{30} {b}^{60} {x}^{40} {y}^{90} + {a}^{10}) \\ 6 {x}^{40} {a}^{10} (4 {a}^{20} {b}^{60} {x}^{40} {y}^{90} + 1)$
