Question

2. Find the following products and then evaluate when x = 2, y = -1
(ii) -11x[2y^5-3/11x^2y^2]
​

Answer 1

Answer:

Answer is 5/2

Step-by-step explanation:

x = 2, y = -1

= -11x[2y⁵-3/11x²y²]

= -11(2)[2(-1)⁵-3/11(2)²(-1)²]

= -22[2(-1)-3/11(4)(1)]

= -22[-2-3/11(4)]

= -22[-5/44]

= -22×-5/44

= 5/2
