Question

(3b-y)³
(2a-5x)³
(x²+5)³
(2a³-3b²)³​

Answer 1

Ответ:

${(3b - y) }^{3} = 27 {b}^{3} - 27 {b}^{2} y + 9b {y}^{2} - {y}^{3} \\ (2a - 5x) ^{3} = 8 {a}^{3} - 60 {a}^{2} x + 150a {x}^{2} - 125a {x}^{3} \\ ( {x}^{2} + 5) ^{3} = {x}^{6} + 15 {x}^{5} + 75 {x}^{4} + 125 {x}^{3} \\ (2 {a}^{3} - 3 {b}^{2} ) ^{3} = 8 {a}^{9} - 36 {a}^{6} {b}^{2} + 54 {a}^{3} {b}^{4} - 27 {b}^{6}$
