Question

Determine o valor numérico do polinômio: 5a²b/2 - 4ab²/9 - 3a²b²/6
Para a=2/3 e b=3/5
Me ajudemmmmm

Answer 1

 5*(2/3)²*(3/5)/2 - 4*(2/3)*(3/5)²/9 - 3(2/3)²(3/5)²/6   

=5 * 4/9  *3/10 - 8/3 * 9/225 - 4/3 * 9/150

=60/90 - 72/675 - 36/450

=2/3- 72/675 -54/675

=2/3 -126/675

=50/75 -14/75 =36/75=12/25
