Explicație pas cu pas:

4 : (2,7 - 1,38)^2 = 4 : 1,32^2 = 4 : 1,7424 = 2,29568... aproximativ 2,3

Answer 2

$\bf 4:(2,7 -1,38)^{2}=$

$\bf 4:(1,32)^{2}=$

$\bf 4:\Big(\dfrac{132}{100}\Big)^{2}=$

$\bf 4:\Big(\dfrac{33 \cdot 4}{25\cdot 4}\Big)^{2}=$

$\bf 4:\Big(\dfrac{33}{25}\Big)^{2}=$

$\bf 4:\dfrac{1089}{625}=$

$\bf 4\cdot\dfrac{625}{1089}=$

$\boxed{\bf \dfrac{2500}{1089}}$
