Question

(3x² yz) (- 4 X Y ²Z ²)(-5X³Y ² )​

Answer 1

SOLUCIÓN

$(3 {x}^{2} yz)( - 4x {y}^{2} {z}^{2} )( - 5 {x}^{3} {y}^{2} ) =$

MULTIPLICANDO:

Coeficientes numéricos

$= (3)( - 4)( - 5) = 3(20) = 60$

Variable "x"

${x}^{2} x {x}^{3} = {x}^{2 + 1 + 3} = {x}^{6}$

Variable "y"

$y {y}^{2} {y}^{2} = {y}^{1 + 2 + 2} = {y}^{5}$

Variable "z"

$z {z}^{2} = {z}^{1 + 2} = {z}^{3}$

Uniendo los resultados parciales, se tiene:

$= 60 {x}^{6} {y}^{5} {z}^{3}$
