Question

[24 −12 : (2 −4 )² −70]: (3² −5 )

Answer 1

Resposta:

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

Explicação passo-a-passo:

$\sf{[24 −12 : (2 −4 )² −70]: (3² −5 )}$

$\sf{(24 - 12 \div ( - 2) {}^{2} - 70) \div (3 {}^{2} - 5) }$

$\sf{(24 - 12 \div ( - 2) {}^{2} - 70) \div (9 - 5)}$

$\sf{(24 - 12 \div {2}^{2} - 70) \div (9 - 5) }$

$\sf{(24 - 12 \div {2}^{2} - 70) \div 4 }$

$\sf{(24 - \frac{12}{ {2}^{2} } - 70) \div 4}$

$\sf{(24 - \frac{12}{4} - 70) \div 4 }$

$\sf{(24 - 3 - 70) \div 4}$

$\sf{ - 49 \div 4 = }$

$\rightarrow\boxed{\boxed{\sf{ - 12,25}}}\checkmark$

Answer 2

Resposta:

12,25.

Explicação passo a passo:

[24 − 12 : (2 − 4 )² − 70] : (3² − 5) =

[24 − 12 : (−2 )² − 70] : (9 − 5) =

[24 − 12 : 4 − 70] : 4 =

[24 − 3 − 70] : 4 =

[21 - 70] : 4

49 : 4 =

12,25.
