Answer 1

Răspuns:

$4 ^{12} \times {2}^{13} = {2}^{24} \times {2}^{13} = {2}^{24 + 13} = {2}^{37}$

${3}^{13} \times {9}^{6} = {3}^{13} \times {3}^{12} = {3}^{13 + 12} = {3}^{25}$

${25}^{10} \div {5}^{15} = {5}^{20} \div {5}^{15} = {5}^{20 - 15} = {5}^{5}$

${8}^{20} \div {4}^{30} = {2}^{60} \div {2}^{60} = {2}^{0} = 1$
