Answer 1

Question:

If a = 1 and b = 3, the value of 4a³b² - 3a²b + 4ab - ab.

Answer:

36

Step-by-step explanation:

→ 4a³b² - 3a²b + 4ab - ab

Simply substitute the value of a = 1 and b = 3

→ 4(1)³(3)² - 3(1)²(3) + 4(1)(3) - (1)(3)

→ 4(1)(9) - 3(1)(3) + 4(1)(3) - (1)(3)

→ 4(9) - 3(3) + 4(3) - 3

→ 36 - 9 + 12 - 3

→ (36 + 12) - (9 + 3)

Solve the brackets

→ 48 - 12

On solving we get,

→ 36

Hence, the answer is 36.
