[tex]\sqrt{1 \frac{9}{16} } = \sqrt{25 \div 16} = 5 : 4 = 1,25[/tex]
[tex] \sqrt{2 \frac{1}{4} } = \sqrt{ \frac{9}{4} } = \frac{3}{2} = 1 \frac{1}{2} [/tex]
[tex] \sqrt{5 \frac{19}{25} } = \frac{144}{25} = \frac{12}{5} = 2 \frac{2}{5} [/tex]
Przepraszam, ale mam tego dość.
P. - pierwiastek
P. 3 1/16 = P. 49/16 = 7/4 = 1 3/4
P. 2 2/49 = P. 100/49 = 10/7 = 1 3/7
P. 6 1/4 = P. 25/4 = 5/2 = 2 1/2
P. 2 7/9 = P. 25/9 = 5/3 = 1 2/3
P. 2 9/36 = P. 81/36 = 9/6 = 1 3/6 = 1 1/2
