¡Hola!

Explicación paso a paso:

a)

$( - 2 {)}^{5} .( - 2 {)}^{7} .( - 2) = \\ ( - 2 {)}^{5 + 7 + 1} = ( - 2 {)}^{13}$

R : (-2)^13

b)

$( - 3 {)}^{4} .3.( - 3 {)}^{2} = \\ {3}^{4} .3. {3}^{2} = \\ {3}^{4 + 1 + 2} = {3}^{7}$

R : 3^7

c)

$( - 5). ( - 5 {)}^{3} .( - 5 {)}^{2} = \\ ( - 5 {)}^{1 + 3 + 2} = \\ ( - 5 {)}^{6} = {5}^{6}$

R : 5^6

d)

${ 3}^{7} \div {3}^{5} = \\ {3}^{7 - 5} = {3}^{2}$

R : 3^2

e)

$( - 3 {)}^{12} \div {3}^{5} = \\ {3}^{12} \div {3}^{5} = \\ {3}^{12 - 5} = {3}^{7}$

R : 3^7

f)

$( - 7 {)}^{5} \div ( - 7 {)}^{5} = \\ ( - 7 {)}^{5 - 5} = \\ ( - 7 {)}^{0} = 1$

R : 1
