8) Calcule as potencias

a) (5x)^3
b) (2/2x^2)^4
c(m^5 y^4)^6
d) [(-2m^3 x ^4 )^2]^2​

Answer 1

a) $(5x)^{3}$

fica:

${5}^{3} . \: {x}^{3}$

$125 {x}^{3}$

----------------------------------------------------------------------------------------------------

b)$( \frac{2}{2 {x}^{2} } )^{4}$

$\\ \frac{ {2}^{4} }{(2 {x}^{2})^{4} }$

$\frac{16}{16 {x}^{8} }$

$\frac{1}{ {x}^{8} }$

----------------------------------------------------------------------------------------------------

c) $( {m}^{5} {y}^{4} )^{6}$

$( {m}^{5} )^{6} . { ({y}^{4} })^{2}$

${m}^{30}{y}^{24}$

----------------------------------------------------------------------------------------------------

d) $[( - 2 {m}^{3} {x}^{4} )^{2} ]^{2}$

$[4 {m}^{6} {x}^{8} ]^{2}$

$16 {m}^{12} \: {x}^{16}$

è isso.... precisas de explicaçao???
