Answer 2

Explicație pas cu pas:

${19}^{7} : {19}^{2} = {19}^{7 - 2} = {19}^{5}$

${10}^{44} : {10}^{41} = {10}^{44 - 41} = {10}^{3} = 1000$

${3}^{234} : {3}^{228} = {3}^{234 - 228} = {3}^{6}$

${5}^{9} : {5}^{2} = {5}^{9 - 2} = {5}^{7}$

${2}^{11} : {2}^{11} = {2}^{11 - 11} = {2}^{0} = 1$

${128}^{8} : {128}^{7} = {128}^{8 - 7} = {128}^{1} = 128$

${2}^{27} : {2}^{24} = {2}^{27 - 24} = {2}^{3} = 8$

${6}^{31} : {6}^{30} = {6}^{31 - 30} = {6}^{1} = 6$

${9}^{4} : {9}^{2} = {9}^{4 - 2} = {9}^{2} = 81$
