12.

a)
${0.7}^{5} \div {0.7}^{3} = {0.7}^{5 - 3} = {0.7}^{2}$


b)
${4.1}^{11} \div {4.1}^{9} = {4.1}^{11 - 9} = {4.1}^{2}$


c)
${7.8}^{6} \div {7.8}^{5} = {7.8}^{6 - 5} = {7.8}^{1} = 7.8$


d)
${256.31}^{4} \div {256.31}^{4} = {256.31}^{4 - 4} = {256.31}^{0} = 1$


e)

${8.59}^{17} \div {8.59}^{16} = {8.59}^{17 - 16} = {8.59}^{1} = 8.59$


f)
${2.3}^{10} \div {2.3}^{6} \div {2.3}^{2} = {2.3}^{10 - 6 - 2} = {2.3}^{2}$


g)
${8.74}^{6} \div {8.74}^{2} \div {8.74}^{3} = {8.74}^{6 - 2 - 3} = {8.74}^{1} = 8.74$


h)
${10.7}^{5} \times {10.7}^{3} \div {10.7}^{8} = {10.7}^{5 + 3 - 8} = {10.7}^{0} = 1$


i)
${1.4}^{14} \div {1.4}^{7} \times {1.4}^{2} = {1.4}^{14 - 7 + 2} = {1.4}^{7 + 2} = {1.4}^{9}$
