1. (2x + 7)³ 2.(p – 5q)⁵ Tolong dijawab T_T hari ini 1. (2x + 7)³

Jawaban:

${(2x + 7)}^{3} = 1 {(2x)}^{3} {(7)}^{0} + 3 {(2x)}^{2} {(7)}^{1} + 3 {(2x)}^{1} {(7)}^{2} + 1 {(2x)}^{0} {(7)}^{3}$

$= 8 {x}^{3} + 21 (4{x}^{2} ) + 6x.49 + 343$

$= 8 {x}^{3} + 84x^{2} + 294x + 343$

${(p - 5q)}^{5} = 1(p)^{5} ( - 5q)^{0} + 5(p)^{4}( - 5q)^{1} + 10(p)^{3}( - 5q)^{2} + 10(p)^{2} ( - 5q)^{3} + 5(p)^{1} ( - 5q)^{4} + 1(p)^{0} ( - 5q)^{5}$

$= p ^{5} - 25p^{4} q + 250p^{3} q^{2} - 1250p^{2}q^{3} + 3125pq^{4} - 3125q^{5}$
