0,3
Explicație pas cu pas:
[tex]\sqrt{0,81} - \sqrt{0,25} + \sqrt{0,36} - \sqrt{3,24} + \sqrt{2,25} - \sqrt{0,16}[/tex]
[tex]= \sqrt{\frac{81}{100} } - \sqrt{\frac{25}{100} } + \sqrt{\frac{36}{100} } - \sqrt{\frac{324}{100} } + \sqrt{\frac{225}{100} } - \sqrt{\frac{16}{100} }[/tex]
[tex]= \frac{9}{10} - \frac{5}{10} + \frac{6}{10} - \frac{18}{10} + \frac{15}{10} - \frac{4}{10}[/tex]
[tex]= \frac{3}{10}[/tex]
= 0,3
