Explicação passo-a-passo:

$\textsf{ \{ [ ( 8 x 4 + 3 )} \div \timesf {7 + (\:3 + 15 } \div \textsf{ 5 ) x 3 ] x 2 - ( 19 - 7 ) } \div \textsf{ 6 \} x 2 + 12 }$

$\textsf{ \{ [ (32 + 3 )} \div \timesf {7 + (\:3 + 15 } \div \textsf{ 5 ) x 3 ] x 2 - ( 19 - 7 ) } \div \textsf{ 6 \} x 2 + 12 }$

$\textsf{ \{ [ (35 )} \div \timesf {7 + (\:3 + 15 } \div \textsf{ 5 ) x 3 ] x 2 - ( 19 - 7 ) } \div \textsf{ 6 \} x 2 + 12 }$

$\textsf{ \{ [ 5 + (\:3 + 15} \div \textsf{ 5 ) x 3 ] x 2 - ( 19 - 7 ) } \div \textsf{ 6 \} x 2 + 12 }$

$\textsf{ \{ [ 5 + (\:3 + 3 ) x 3 ] x 2 - ( 19 - 7 ) } \div \textsf{ 6 \} x 2 + 12 }$

$\textsf{ \{ [ 5 + 6 x 3 ] x 2 - ( 19 - 7 ) } \div \textsf{ 6 \} x 2 + 12 }$

$\textsf{ \{ [ 5 + 18 ] x 2 - ( 19 - 7 ) } \div \textsf{ 6 \} x 2 + 12 }$

$\textsf{ \{ 23 x 2 - ( 19 - 7 ) } \div \textsf{ 6 \} x 2 + 12 }$

$\textsf{ \{ 46 - ( 19 - 7 ) } \div \textsf{ 6 \} x 2 + 12 }$

$\textsf{ \{ 46 - (12) } \div \textsf{ 6 \} x 2 + 12 }$

$\textsf{ \{ 46 - 2 \} x 2 + 12 }$

$\textsf{ \{ 44 \} x 2 + 12 }$

$\textsf{ 88 + 12 }$

$\boxed{\boxed{\textsf{ 100 }}}$

$\textsf{ \{ [ ( 6 x 4 x 7 )} \div \textsf{3 + 9 ]} \div \textsf{5 \} x 13}$

$\textsf{ \{ [ ( 24 x 7 )} \div \textsf{3 + 9 ]} \div \textsf{5 \} x 13}$

$\textsf{ \{ [ ( 168 )} \div \textsf{3 + 9 ]} \div \textsf{5 \} x 13}$

$\textsf{ \{ [ 56 + 9 ]} \div \textsf{5 \} x 13}$

$\textsf{ \{ [ 65 ]} \div \textsf{5 \} x 13}$

$\textsf{13 x 13}$

$\boxed{\boxed{\textsf{ 169 }}}$

Answer 2

Explicação passo-a-passo:

f)

{[(8 x 4 + 3) ÷ 7 + (3 + 15 ÷ 5) x 3] x 2 - (19 - 7) ÷ 6} x 2 + 12

= {[(32 + 3) ÷ 7 + (3 + 3) x 3] x 2 - 12 ÷ 6} x 2 + 12

= {[35 ÷ 7 + 6 x 3] x 2 - 2} x 2 + 12

= {[5 + 18] x 2 - 2} x 2 + 12

= {23 x 2 - 2} x 2 + 12

= {46 - 2} x 2 + 12

= 44 x 2 + 12

= 88 + 12

= 100

g)

{[(6 x 4 x 7) ÷ 3 + 9] ÷ 5} x 13

= {[(24 x 7) ÷ 3 + 9] ÷ 5} x 13

= {[168 ÷ 3 + 9] ÷ 5} x 13

= {[56 + 9] ÷ 5} x 13

= {65 ÷ 5} x 13

= 13 x 13

= 169
