Answer 1

Explicație pas cu pas:

a)

${2}^{28} - {2}^{28} = 0$

b)

${3}^{20} \div {3}^{19} = 3$

c)

${5}^{56} \div {5}^{54} = {5}^{2} = 25$

d)

${7}^{49} \div {7}^{77 - 35} = {7}^{49} \div {7}^{42} = {7}^{7}$

e)

${13}^{104} \div {13}^{104} = 1$

f)

${7}^{13} \div {7}^{168} = {7}^{ - 155} = \frac{1}{ {7}^{155} }$

g)

${2}^{72} \div {2}^{48} = {2}^{24}$

h)

${3}^{82 - 43} = {3}^{39}$
