aratati ca(3-3 x 1/5 x 1/3) x 5/14 = 1

Explicație pas cu pas:

[tex](3 - 3 \times \frac{1}{5} \times \frac{1}{3} ) \times \frac{5}{14} = 1 \\ (3 - \frac{3}{5} \times \frac{1}{3} ) \times \frac{5}{14} = 1 \\ (3 - \frac{1}{5} ) \times \frac{5}{14} = 1 \\ (\frac{15}{5} - \frac{1}{5} ) \times \frac{5}{14} = 1 \\ \frac{14}{5} \times \frac{5}{14} = 1[/tex]

Explicație pas cu pas:

[tex] \bf \bigg(3 - 3 \cdot \dfrac{1}{5} \cdot \dfrac{1}{3} \bigg)\cdot \dfrac{5}{14} = [/tex]

[tex] \bf \bigg(3 - \not3 \cdot \dfrac{1}{5} \cdot \dfrac{1}{ \not3} \bigg)\cdot \dfrac{5}{14} = [/tex]

[tex] \bf \bigg(3 - 1 \cdot \dfrac{1}{5} \cdot \dfrac{1}{1} \bigg)\cdot \dfrac{5}{14} = [/tex]

[tex] \bf \bigg( ^{5)} 3 - \dfrac{1}{5} \bigg)\cdot \dfrac{5}{14} = [/tex]

[tex]\bf \dfrac{15 - 1}{5} \cdot \dfrac{5}{14} = \dfrac{ \not14}{\not5} \cdot \dfrac{\not5}{\not14} = \red{ \underline{1}}[/tex]
