Question

if x=2 y= -3 z= -2 then find the value of 2xy²z - 3xy + 4z​

Answer 1

Answer:

Value = -62

Step-by-step explanation:

Given that ;

2xy²z - 3xy + 4z

• x = 2
• y = -3
• z = -2

Substitute ;

The given values in the given equation ,

2xy²z - 3xy + 4z

2(2)(-3)²(-2) - 3(2)(-3) + 4(-2)

4(9)(-2) - 3(-6) - 8

-72 + 18 - 8

-62

Answer 2

Answer:

If x=2 y= -3 z= -2 then the value of 2xy²z - 3xy + 4z​ is -98.

Step-by-step explanation:

Given: x=2 y= -3 z= -2

Find the value of 2xy²z - 3xy + 4z​

Put x=2 y= -3 z= -2  in

2xy²z - 3xy + 4z​

$= 3 (2)(-3)^2 (-2) - 3 (2)(-3) + 4(-2)$

= 6 (9) (-2) - 6(-3) - 8

= 54 (-2) + 18 - 8

= - 108 + 10

= - 98
