Question

Determine o resultado da expressão numérica abaixo

Answer 1

Resposta:

$\sf 4 \cdot \bigg[\sqrt{\dfrac{1}{16} } + \left \big(2 \cdot \sqrt{72} \right \big) - \left \bigg( 4 \cdot \sqrt{\dfrac{1}{256} } \right) \bigg] =$

$\sf 4 \cdot \bigg[\sqrt{\dfrac{1}{16} } + \left \big(2 \cdot \sqrt{72} \right \big) - \left \bigg( 4 \cdot \dfrac{1}{16} } \right) \bigg] =$

$\sf 4 \cdot \bigg[\sqrt{\dfrac{1}{16} } + \left \big(2 \cdot \sqrt{72} \right \big) - \left \dfrac{4}{16} } \bigg] =$

$\sf 4 \cdot \bigg[\sqrt{\dfrac{1}{16} } + \left \big(2 \cdot \sqrt{72} \right \big) - \left \dfrac{1}{4} } \bigg] =$

$\sf 4 \cdot \bigg[ \dfrac{1}{4} } + \left \big(2 \cdot \sqrt{72} \right \big) - \left \dfrac{1}{4} } \bigg] =$

$\sf 4 \cdot \bigg[ \left \big(2 \cdot \sqrt{72} \right \big) } \bigg] =$

$\sf 4 \cdot \bigg[ 2 \cdot \sqrt{72} \bigg] =$

$\boldsymbol{ \sf \displaystyle 8 \cdot \sqrt{72} }$
