Explicație pas cu pas:
a)
[tex] {2}^{28} - {2}^{28} = 0[/tex]
b)
[tex] {3}^{20} \div {3}^{19} = 3[/tex]
c)
[tex] {5}^{56} \div {5}^{54} = {5}^{2} = 25 [/tex]
d)
[tex] {7}^{49} \div {7}^{77 - 35} = {7}^{49} \div {7}^{42} = {7}^{7} [/tex]
e)
[tex] {13}^{104} \div {13}^{104} = 1[/tex]
f)
[tex] {7}^{13} \div {7}^{168} = {7}^{ - 155} = \frac{1}{ {7}^{155} } [/tex]
g)
[tex] {2}^{72} \div {2}^{48} = {2}^{24} [/tex]
h)
