Answer 1

Explicație pas cu pas:

${8}^{17} : {8}^{11} = {8}^{17 - 11} = {8}^{6}$

${5}^{31} : {5}^{23} = {5}^{31 - 23} = {5}^{8}$

${12}^{45} : {12}^{27} = {12}^{45 - 27} = {12}^{18}$

${7}^{19} : {7}^{15} : {7}^{2} = {7}^{19 - 15 - 2} = {7}^{2} = 49$

${2}^{28} : {2}^{13} : {2}^{5} = {2}^{28 - 13 - 5} = {2}^{10} = 1024$

${9}^{15} : {9}^{11} : {9}^{3} = {9}^{15 - 11 - 3} = {9}^{1} = 9$

${15}^{12} \cdot {15}^{6} : {15}^{13} = {15}^{12 + 6 - 13} = {15}^{5}$

${3}^{42} : {3}^{31} \cdot {3}^{9} = {3}^{42 - 31 + 9} = {3}^{20}$
