Răspuns:

${2}^{43} \times {4}^{15} = {2}^{43} \times ( {2}^{2} )^{15} = {2}^{43} \times {2}^{30} = {2}^{43 + 30} = {2}^{73}$

${2}^{74} \div {2}^{31} = {2}^{74 - 31} = {2}^{43}$

${2}^{44} \times {2}^{45} = {2}^{89}$

${3}^{11} \times {3}^{24} = {3}^{35}$

${3}^{72} \div {3}^{12} = {3}^{60}$

${2}^{18} \times {2}^{60} \div {2}^{15} = {2}^{63}$

${2}^{30} \times {2}^{30} \div {2}^{40} = {2}^{20}$

${3}^{17} \times {3}^{48} \div {3}^{18} = {3}^{47}$
