Question

a = -4 and b = 5 then find the value of 50 a^2 b + 40 a b^3 - 20 ab​

Answer 1

Step-by-step explanation:

50a²b + 40ab³ - 20ab

For, a = -4 and b=5

50 ×(-4)² × 5 + 40×(-4)×5³ - 20×-4×5

= 4000 - 20,000 + 400

= 4400 - 20,000

= -15,600

Answer 2

Answer:

-15600

Step-by-step explanation:

Given:-

• a = -4, b = 5,
• To find value of :- 50a²b+40ab³-20ab

→Solⁿ

=> 50a²b+40ab³-20ab = 50×(-4)²×5+40(-4)×(5)³-20(-4)(5)

=> 50×16×5+40×-4×125-20×-20

=> 50×80+40×-500+400

=> 4000+400-20000

= -15600
