Question

If x=2 and y=1 then find the value of : (-4x^2y^3)(-5x^2y)
​

Answer 1

Answer:

320

Step-by-step explanation:

x = 2

y = 1

- 4x^2 y^3

= - 4 ( 2 )^2 ( 1 )^3

= -4 ( 4 ) ( 1 )

= - 16

- 5x^2 y

= - 5 ( 2 )^2 ( 1 )

= - 5 ( 4 ) ( 1 )

= - 20

( - 4x^2 y^3 ) ( - 5x^2 y )

= ( - 16 ) ( - 20 )

= 320
