Answer 1

Resposta:

Bases iguais = soma os expoentes

Explicação passo-a-passo:

$a) 8^3 \cdot 8^2 = 8^{3 + 2} = 8^{5} \\b)1^4. 1^5 = 1^{4 + 5} = 1^{9}\\c)(0,2)^7. (0,2)^5 = (0,2)^{7 + 5} = (0,2)^{12}\\d) 5^6. 5^2. 5^4= 5^{6 + 2 + 4} = 5^{12}\\e)6^3 . 6 = 6^{3 + 1} = 6^{4}\\f)\left(\frac{1}{5}\right)^{8} . \left(\frac{1}{5}\right) = \left(\frac{1}{5}\right)^{8 + 1} = \left(\frac{1}{5}\right)^{9}\\g)3^7. 3^2 = 3^{7 + 2} = 3^{9}\\h) 9^3. 9 . 9^8= 9^{3 + 1 + 8} = 9^{12}\\i) 0^3 .0^12 =​ 0^{3 + 12} = 0^{15} = 0$
