Me ajuda??
a)[(+5)·(-2)]^5=
b)[(-3)·(-6)]^7=
c)[(-2)^3·(+3)^4]^2=
d)[(+4)·(-5)^3]^3=
e)[(-2a^3)^2=

Answer 1

a)[(+5)·(-2)]^5=

${((5) \times ( - 2))}^{5} = {( - 10)}^{5} = 100000$

b)[(-3)·(-6)]^7=

${(( - 3) \times ( - 6))}^{7} = {18}^{7} = 612220032$

c)[(-2)^3·(+3)^4]^2=

${( {( - 2)}^{3} \times {(3)}^{4} ) }^{2} = {(( - 8) \times (81))}^{2} = {( - 648)}^{2} = 419904$

d)[(+4)·(-5)^3]^3=

${((4) \times {( - 5)}^{3} )}^{3} = {(4 \times ( - 125))}^{3} = {( - 500)}^{3} = - 125000000$

e)[(-2a^3)^2=

${( - 2 {a}^{3}) }^{2} = 4 {a}^{6}$
