Explicație pas cu pas:
a)
[tex]({2}^{7} ) \div (2 \times {2}^{10} ) = ( {2}^{7} ) \div ( {2}^{11} ) = {2}^{ - 4} [/tex]
Explicatie:
[tex] {2}^{2} \times {2}^{10} = {2}^{2 + 10} = {2}^{12} [/tex]
b)
[tex] {( {6}^{10}) }^{5} \div (6 \times {6}^{12} \times {6}^{18} ) = {6}^{50} \div {6}^{31} = {6}^{19} [/tex]
