Question

Rezultatul calculului √5,76x0,(5)-0,4 este....... vreau detailat

Answer 1

[tex]\sqrt{5,76}*0,(5)-0,4=\\\\ = \sqrt{ \frac{576}{100} } * \frac{5}{9} - \frac{4}{10}\\\\ = \frac{ \sqrt{576}}{10} * \frac{5}{9} - \frac{4}{10}\\\\ =\frac{24*5 }{90} - \frac{4}{10}\\\\ = \frac{120}{90}- \frac{36}{90} \\\\=\frac{84}{90} \\\\ =0,9(3) [/tex]

Answer 2

√5,76×0,(5)-0,4=
=$\sqrt{ \frac{576}{100} } * \frac{5}{9} - \frac{4}{10}= \frac{ \sqrt{576}}{10} * \frac{5}{9} - \frac{4}{10} =\frac{24*5 }{90} - \frac{4}{10} = \frac{120}{90}- \frac{36}{90} =\frac{84}{90}$
=0,9(3)
