Question

помогите пожалуйста 15.4

Answer 1

$1) : : : 0.125 {m}^{2} {n}^{3} - 0.25mn + 0.625 {m}^{2} n = 0.125mn(m {n}^{2} - 2 + 5m ) \ 2) : : : 328 { t }^{2} {k}^{3} + 82 {t}^{2} {k}^{2} = 82{t}^{2} {k}^{2} (4k + 1) \ 3) : : : 0.09 {m}^{6} {n}^{5} +0 .27 {m}^{3} {n}^{8} - 0.09{m}^{3} {n}^{5} = 0.09{m}^{3} {n}^{5} ({m}^{3} + 3{n}^{3} - 1)$
$4) : : : 1.6 {t}^{11} {k}^{4} - 3.2{t}^{10} k + 0.8{t}^{9} k = 0.8{t}^{9} k (2 {t}^{2} {k}^{3} - 4t + 1) \ 5) : : : 14 {m}^{4} - 49 {m}^{2} nk + 7 {m}^{2} n) = 7 {m}^{2} (2 {m}^{2} - 7nk + n) \ 6) : : : - 8 {t}^{ 8 } {k}^{3} y + 64 {t}^{3 } {k}^{8} - 4 {t}^{3} {k}^{3} = - 4 {t}^{3} {k}^{3}(2 {t}^{5} y - 16 {k}^{5} + 1)$
