Question

(7xy 3 – 8x²y2)x(-2xy?) for x = -1, y = 2​

Answer 1

Answer :- - 184 is the answer

Step by Step explanation :-

Substituting the value of x =-1 and y = 2 , we get :-

=> (7 × -1 × 2 - 8 × -1^2 × 2 × 2) × (-2×-1×2)

=> (-14 - 8 × 1 × 4 ) × (2×2)

=>( - 14 - 8 × 4) × 4

=>( -14 - 32) × 4

=> -46 × 4

=> - 184

Thus the answer is -184
