alguém me ajuda por favor a pra amanhã e vale nota ​

Answer 1

Resposta:

$\sf{segue \: abaixo \: a \: resposta}$

Explicação passo-a-passo:

$\sf{{10+ [5. (4+2.5) -8].2}-6³:2-4²}$

$\sf{2x5 = 10}$

$\sf{(10 + (5(4 + 10) - 8)x2) - {6}^{3} \div 2 - {4}^{2} }$

$\sf{ {6}^{3} \div 4 = \frac{ {6}^{3} }{2} }$

$\sf{(10 + (5(4 + 10) - 8)x2) - \frac{ {6}^{3} }{2} - {4}^{2} }$

$\sf{ {4}^{2} = 16}$

$\sf{(10 + (5(4 + 10) - 8)x2) - \frac{ {6}^{3} }{2} - 16}$

$\sf{4 + 10 = 14}$

$\sf{(10 + (5x14 - 8)x2) - \frac{ {6}^{3} }{2} - 16}$

$\sf{5x14 = 70}$

$\sf{(10 + (70 - 8)x2) - \frac{ {6}^{3} }{2} - 16 }$

$\sf{70 - 8 = 62}$

$\sf{(10 + 62x2) - \frac{ {6}^{3} }{2} - 16 }$

$\sf{62x2 = 124}$

$\sf{(10 + 124) - \frac{ {6}^{3} }{2} - 16}$

$\sf{10 + 124 = 134}$

$\sf{134 - \frac{ {6}^{3} }{2} - 16 }$

$\sf{134 - 16 =118 }$

$\sf{118 - \frac{ {6}^{3} }{2} }$

$\sf{ {6}^{3} = 216}$

$\sf{118 - \frac{216}{2} }$

$\sf{ \frac{216 \div 2 \: = \: 108}{ 2 \div 2 \: = \: 1} = \frac{108}{1} = 108 }$

$\sf{118 - 108 = }$

$\boxed{\boxed{{\sf{10}}}}$
