Question

If x=1,y=-2,Z=3 then 3xy4-15x2y+4z​

Answer 1

Answer:

= 96

Step-by-step explanation:

3xy4-15x2y+4z

3(1)(-2)4 - 15(1)2(-2) + 4(3)

3(-2)4 - 30(-2) + 12

-24 + 60 + 12

-24 + 72

= 96

Answer 2

Answer:

90

Step-by-step explanation:

3 (1)(-2)^4 - 15 (1)^2 (-2) + 4(3)

= 3 (16) - (-30) + 12

= 48 + 30 + 12

=> 90
