Explicație pas cu pas:
Salutare!
[tex]\bf \dfrac{98 \cdot (-15)}{-14\cdot (20-4\cdot10)}[/tex]
[tex]\bf \dfrac{-1470}{-14\cdot (20-40)} =[/tex]
[tex]\bf \dfrac{-1470}{-14\cdot (-20)} =[/tex]
[tex]\bf \dfrac{-1470}{280} =[/tex]
[tex]\bf \dfrac{-\not1470}{\not280} =[/tex]
[tex]\bf \dfrac{-21}{4} =[/tex]
[tex]\boxed{\bf -\dfrac{21}{4}}[/tex]
