I. 3b (4b + 5ab - 2b3) =
m. 5x2 (4x2 + 2x4 - 10x) =​

Answer 1

Procedimientos:

1.

$2xa \: (3 xb) = 3(2)ab \: (x)(x) = 6ab {x}^{2}$

2.

$15abz \: (8ab) = 15(8)(a)(a)(b)(b)z = 120 {a}^{2} {b}^{2} z$

3.

$3c(0bc) = 3(0)(b)(c)(c) = 0$

4.

$(2m - 3m ^{0} - 5 m 4n ^{0} )( - 7 {m}^{2} + 6 {m}^{0} - 11 {m}^{0} n) \\ = 126m - 108m + 198mn + 21 {m}^{2} - 18 + 33n$

5.

$526 \times 526 = 276676$

6.

$3b \: (4b + 5ab - 2 {b}^{3} ) \\ = 12 {b}^{2} + 15a {b}^{2} - 6 {b}^{4 }$

7.

$5 {x}^{2} (4 {x}^{2} + 2 {x}^{4} - 10x) \\ = 20 { x}^{4} + 10 {x}^{6} - 50 {x}^{3}$
