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.
