​

Answer 1

Explicação passo-a-passo:

${7}^{2} {7}^{6} = {7}^{ 8} \\ \\ 5 \times {5}^{3} = {5}^{1} \times {5}^{3} = {5}^{ 1+ 3} = {5}^{4} \\ \\ {8}^{2} \times 8 = {8}^{2} \times {8}^{1} = {8}^{2 + 1} = {8}^{3} \\ \\ {3}^{0} \times {3}^{0} = 1 \times 1 = 1 \\ \\ {4}^{3} \times 4 \times {4}^{2} = {4}^{3} \times {4}^{1} \times {4}^{2} = {4}^{3 + 1 + 2} = {4}^{6} \\ \\ {a}^{2} {a}^{2} {a}^{2} = {a}^{ 2+ 2 + 2} = {a}^{6} \\ \\ m \times m \times {m}^{2} = {m}^{1} \times {m}^{1} \times {m}^{2} = {m}^{1 + 1 + 2} = {m}^{4}$
