Aratati ca (fractie 3pe2-1)²+fractie3pe4=1

Answer 1

$( \frac{3}{2} - 1) ^{2} + \frac{3}{4} = 1 \\ \\ (\frac{1}{2}) ^{2} + \frac{3}{4} = 1 \\ \\ \frac{1}{ {2}^{2} } + \frac{3}{4} = 1 \\ \\ \frac{1}{4} + \frac{3}{4} = 1 \\ \\ 1 = 1$

Answer 2

$( \frac{3}{2} - 1)^{2} + \frac{3}{4} = 1 \\ \\ ( \frac{3}{2} - \frac{2}{2} )^{2} + \frac{3}{4} = 1 \\ \\ ( \frac{1}{2} )^{2} + \frac{3}{4} = 1 \\ \\ \frac{1 + 3}{4} = 1 \\ \\ \frac{4}{4} = 1 \\ \\ 1 = 1 \: adevarat$
