Question

помогите пожалуйста решить все​

Answer 1

$a) \: x {y}^{2} + {x}^{2} {y}^{3} = x {y}^{2} (1 + xy) \\ b) \: {a}^{4} {b}^{2} - {a}^{2} {b}^{4} = {a}^{2} {b}^{2} ( {a}^{2} - {b}^{2} ) = {a}^{2} {b}^{2} (a - b)(a + b) \\ c) \: {m}^{2} {n}^{2} + m {n}^{3} = m {n}^{2} (m + n) \\ d) \: {a}^{3} {b}^{2} + {a}^{5} {b}^{3} = {a}^{3} {b}^{2} (1 + {a}^{2} b) \\ e) \: {c}^{3} {d}^{2} - {c}^{4} {d}^{2} = {c}^{3} {d}^{2} (1 - c) \\ f) \: - {x}^{5} {y}^{3} - {x}^{3} {y}^{5} = - {x}^{3} {y}^{3} ( {x}^{2} + {y}^{2} )$
