Question

Find the value of the given expressions if 'x=-1, y=-2' 3x^3-2x^2y+3xy^2-5​
pls help me

Answer 1

Answer:

x= -1, y = -2

3x^3 - 2x^2y + 3xy^2 - 5

=> 3(-1)^3 - 2(-1)^2(-2) + 3(-1)(-2)^2 - 5

=> 3(-1) - (-2)^(-4) + 36 - 5

=> -3 -(1/-2)^4 + 36 - 5

=> -3 - 1/16 + 36 - 5

=> -49/16 + 36 - 5

=> 527/16 - 5

=> 447/16

=> 27.93

Ans. 27.93
