Question

√(3,66666-1,22222):1,1-0,44444

Answer 1

$\frac{ \sqrt{3.6666666666 - 1.222222222} }{1.1} - 0.444444444 \\ = \frac{ \sqrt{ \frac{36 - 3}{9} - \frac{12 - 1}{9} } }{ \frac{11}{10} } - \frac{4}{10} \\ = \frac{ 10\sqrt{ \frac{33}{9} - \frac{11}{9} } }{11} - \frac{4}{10} \\ = \frac{10 \sqrt{ \frac{22}{9} } }{11} - \frac{4}{10} \\ = \frac{10 \sqrt{22} }{33} - \frac{4}{10} \\ = \frac{100 \sqrt{22} - 132 }{330} \\ = \frac{50 \sqrt{22} - 66}{165}$
