Qual é a resposta de 2{2⁴[5+(8²+9²)-81]-3²]

Answer 1

Olá!

$\\ \displaystyle \mathsf{2 \cdot \left \{ 2^4 \cdot \left [ 5 + \left ( 8^2 + 9^2 \right ) - 81 \right ] - 3^2 \right \} =} \\\\ \mathsf{2 \cdot \left \{ 16 \cdot \left [ 5 + \left ( 64 + 81 \right ) - 81 \right ] - 9 \right \} =} \\\\ \mathsf{2 \cdot \left \{ 16 \cdot \left [ 5 + 64 + 81 - 81 \right ] - 9 \right \} =} \\\\ \mathsf{2 \cdot \left \{ 16 \cdot 69 - 9 \right \} =} \\\\ \mathsf{2 \cdot \left \{ 1104 - 9 \right \} =} \\\\ \mathsf{2 \cdot 1095 =} \\\\ \boxed{\mathsf{2190}}$

$2\{2^4[5+(8^2+9^2)-81]-3^2\}= \\ \\ 2\{16*[5+(64+81)-81]-9\}= \\ \\ 2\{16*[5+64+81-81]-9\}= \\ \\ 2\{16*[5+64]-9\}= \\ \\ 2\{16*[69]-9\}= \\ \\ 2\{1104-9\}= 2*1095= \boxed{2190}$
