Răspuns: Ai mai jos demonstrația
Explicație pas cu pas:
[tex]\large\bf a = \dfrac{9}{2}\cdot \dfrac{8}{3} = \dfrac{9\cdot8}{2\cdot3} =\Bigg(\dfrac{72}{6}\Bigg)^{(6}\implies \pink{\boxed{\bf a =12}}[/tex]
[tex]\it~~[/tex]
[tex]\large \bf b = -8 +2 \implies \green{\boxed{\bf b = -6}}[/tex][tex]\it~~[/tex]
[tex]\it~~~[/tex]
[tex]\large\bf \dfrac{a}{b}= \dfrac{12}{-6} =-\dfrac{12}{6}=-\dfrac{\not12}{\not6}\implies \red{\boxed{\bf \dfrac{a}{b} =-2}}[/tex]
Bafta multa!
