por favor Alguém mim ajuda ñ tou conseguindo resolver essa Expressão ​

Answer 1

$~\huge\mid{\boxed{\bf{\blue{Matem\acute{a}tica}}}\mid}$

$(( \frac{ {10}^{7} \times {10}^{13} }{ {10}^{12} \times {10}^{5} \times {10}^{2} } {)}^{4} {)}^{5} + ( \frac{ {10}^{ - 4} \times {10}^{6} }{ {10}^{3} \times {10}^{ - 11} } {)}^{2}$

• Usando a propriedade de potência $\color{green} {{  }}( {2}^{2} {)}^{2} = {2}^{2 \times 2} = {2}^{ {4}^{} }$

$( \frac{ {10}^{7} \times {10}^{13} }{ {10}^{12} \times {10}^{5} \times {10}^{2} } {)}^{4 \times 5} {}^{} + ( \frac{ {10}^{ - 4} \times {10}^{6} }{ {10}^{3} \times {10}^{ - 11} } {)}^{2}$

$( \frac{ {10}^{7} \times {10}^{13} }{ {10}^{12} \times {10}^{5} \times {10}^{2} } {)}^{20} {}^{} + ( \frac{ {10}^{ - 4} \times {10}^{6} }{ {10}^{3} \times {10}^{ - 11} } {)}^{2}$

• Use a propriedade $\color{green} {{  }} {2}^{2} \times {2}^{2} = {2}^{2 + 2} = {2}^{4}$

$(\frac{ {10}^{7 + 13} }{ {10}^{12 + 5 + 2} } {)}^{20} + ( \frac{ {10}^{ - 4 + 6} }{ {10}^{3 - 11} } {)}^{2}$

$(\frac{ {10}^{7 + 13} }{ {10}^{12 + 5 + 2} } {)}^{20} + ( \frac{ {10}^{ 2} }{ {10}^{ - 8} } {)}^{2}$

$(\frac{ {10}^{20} }{ {10}^{19} } {)}^{20} + ( \frac{ {10}^{ 2} }{ {10}^{ - 8} } {)}^{2}$

• Use a propriedade $\color{green} {{  }} \frac{ {2}^{2} }{ {2}^{2} } = {2}^{2 - 2} = {2}^{0}$

$(\frac{ {10}^{20} }{ {10}^{19} } {)}^{20} + ( {10}^{2 - ( - 8)} {)}^{2}$

• Faça o jogo de sinal: (-) × (-) = (+)

$( \frac{ {10}^{20} }{ {10}^{19} } {)}^{20} + ( {10}^{2 + 8} {)}^{2}$

$( \frac{ {10}^{20} }{ {10}^{19} } {)}^{20} + ( {10}^{10} {)}^{2}$

$( {10}^{20 - 19} {)}^{20} + ( {10}^{10} {)}^{2}$

$( {10}^{1} {)}^{20} + ( {10}^{10} {)}^{2}$

${10}^{1 \times 20} + ( {10}^{10} {)}^{2}$

${10}^{20} + {10}^{10 \times 2}$

${10}^{20} + {10}^{20}$

• Acrescente o coeficiente 1

$1 \times {10}^{20} + 1 \times {10}^{20}$

$(1 + 1) \times {10}^{20}$

Resposta: $\color{green} \boxed{{ 2 \times {10}^{20} }}$
