Question

помгите пожалуйста!!!!!!!!!!!!!!

Answer 1

Здравствуйте!

#1
$a) \: p(a + b) = pa + pb \\ b) \: - y(k + c) = - yk - yc \\ v) \:a(k + c - 3) = ak + ac - 3a \\ g) \: - x(a - b + 1) = - xa + xb - x$

#2
$a) \:5a {}^{2}(2 - a) = 10a {}^{2} - 5a {}^{3} \\ b) \: - 8b {}^{3}(b - 2b {}^{2} ) = - 8b {}^{4} + 16b {}^{5} \\ v) \: - 7x {}^{3} (x {}^{5} + 3x) = - 7x {}^{8} - 21x {}^{4} \\ g) \: (y {}^{15} + y {}^{20} ) \times 12y {}^{23} = 12y {}^{38} + 12y {}^{43}$

#3

$a) \: 2m {}^{4}(m {}^{5} - m {}^{3} - 1) = 2m {}^{9} - 2m {}^{7} - 2m {}^{4} \\ b) \: - 3c(c {}^{3} + c - 4) = - 3c {}^{4} - 3c {}^{2} + 12c \\ v) \: (8a {}^{2} - 4a + 16) \times 0.25a = 2a {}^{3} - a {}^{2} + 4a$
$g) \: 2x(3x {}^{2} + 5xy - y {}^{2} ) = 6x {}^{3} + 10x {}^{2} y - 2xy {}^{2} \\ d) \: b {}^{5} (b {}^{6} - 5b {}^{3} + b - 3) = b {}^{11} - 5b {}^{8} + b {}^{6} - 3b {}^{5} \\ e) \: - 9p( - 2p {}^{4} + p {}^{2} - 2p + 1) = 18p {}^{5} - 9p {}^{3} + 18p {}^{2} - 9p$

Удачи в учёбе!!!
