Question

Me ajudem nessa questão pfvr!!!​

Answer 1

Resposta:

Explicação passo a passo:

$1)$

$3^{(8+2)}:3^{(9-3)}=3^{10}: 3^{6} =3^{(10-6)}=3^{4}=81$

$2)$

$a)\:(+4)^{(10+3)} =(+4)^{13}$

$b)\:(-3)^{(5-2)} =(-3)^{3}$

$c)\:(-3)^{3.2} =(-3)^{6}$

$d)\:(+3)^{(9+1)} =(+3)^{10}$

$e)\:(-7)^{(8-6)} =(-7)^{2}$

$f)\:(-7)^{5.3} =(-7)^{15}$

$Observacoes...Regras...$

$a^{m}\:.\:a^{n}=a^{(m+n)}$

$a^{m}\::\:a^{n}=a^{(m-n)}$

$(a^{m})^{n}=a^{m.n}$
