Question

Calcule os produtos representando o cálculo

A) (m²-1).(m⁴-5)

B) (X⁵-2).(x³+8)
C) (ab-2y).(ab+2y)

Answer 1

Explicação passo-a-passo:

a)

$( {m}^{2} - 1) \times ( {m}^{4} - 5)$

${m}^{2} \times ( {m}^{4} - 5) - 1( {m}^{4} - 5)$

$\boxed{\boxed{\boxed{\red{\boxed{ {m}^{6} - {5m}^{2} - {m}^{4} + 5 }}}}}$

b)

$( {x}^{5} - 5) \times ( {x}^{3} + 8)$

${x}^{5} \times ( {x}^{3} + 8) - 5( {x}^{3} + 8)$

$\boxed{\boxed{\boxed{\red{\boxed{ {x}^{8} + {8x}^{5} { - 5x}^{3} - 40}}}}}$

c)

$(ab - 2y) \times (ab + 2y)$

${(ab)}^{2} - {(2y)}^{2}$

$\boxed{\boxed{\boxed{\red{\boxed{ {a}^{2} {b}^{2} { - 4y}^{2} }}}}}$
