Question

Calcule a)4x(sobre2)×4x(sobre2) b)2x (sobre3)×2x (sobre3 c)(-3x)×(-3x) d)4x(sobre2))(sobre2) f)(2x (sobre3)(sobre2) g)(-3x)(sobre2) h)(-2x)(sobre3) d)(-2x)×(-2x)×(-2x) e)

Answer 1

a)

$4 {x}^{2} \times 4{x}^{2} = 4 {x}^{4}$

b)

$2 {x}^{3} \times 2 {x}^{3} = 2 {x}^{6}$

c)

$- 3x \times - 3x = - 3 {x}^{2}$

d)${ {4}^{2} }^{2} = {4}^{4}$

f)

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

g)

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

h)

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

d)(a segunda letra d)

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