Question

Qual é a resposta K = [-7 + 14 : (5- √49)] :7 ?

Answer 1

Resposta:

$\sf K = \big [-7 + 14 : \big(5- \sqrt{49}\big ) \big] \div 7$

$\sf K = \big [-7 + 14 : \big(5 - 7\big ) \big] \div 7$

$\sf K = \big [-7 + 14 : \big( -\, 2\big ) \big] \div 7$

$\sf K = \big [-7 -\; 7 \big] \div 7$

$\sf K = \big [-\; 14 \big] \div 7$

$\sf K = -\; 14 \div 7$

$\boxed{ \boxed { \boldsymbol{ \sf \displaystyle K = -\: 2}}} \quad \gets \mathbf{ Resposta }$
