Answer 1

Resposta:

TODAS SAO 108 CONFIA NO PAI

Answer 2

Resposta:

$a)( - 6 {x}^{2})(3 {x}^{2} ) =$

$= ( - 6) \times 3 \times {x}^{2 + 2} = - 18 {x}^{4}$

$b)( - 2y) \times (5y) =$

$= ( - 2) \times 5 \times {y}^{1 + 1} = - 10 {y}^{2}$

$c)(4 {x}^{2} ) \times (5 {x}^{3} ) =$

$= 4 \times 5 \times {x}^{2 + 3} = 20 {x}^{5}$

$d)(3x) \times ( - 5y) =$

$= 3 \times ( - 5) \times x \times y = - 15xy$

$e)(2y) \times ( - 7y) =$

$= 2 \times ( - 7) \times {y}^{1 + 1} = - 14 {y}^{2}$

$f)( - 2x) \times ( - 3y) =$

$= ( - 2) \times ( - 3) \times x \times y = 6xy$

$g)( - 3xy) \times ( - 2x) =$

$= ( - 3) \times ( - 2) \times {x}^{1 + 1} \times y =$

$= 6 {x}^{2} y$
