Question

Calcule: 4.X^2 + 3.Y^2 -5. K^3
Para: X= 2
Y = -1
K = 0

Answer 1

Olá!

Basta subistituir os valores, resolvendo ....

$4x^{2}\ +\ 3y^{2}\ -\ 5k^{3}\\\\\\4.(2)^{2}\ +\ 3.(-1)^{2}\ -\ 5.(0)^{3}\\\\\\4.4\ +\ 3.1\ -\ 5.0\\\\\\16\ +\ 3\ -\ 0\ =\boxed{\boxed{19}}\\\\\\\\\\\\Bons\ estudos!\ :)$
