### Instruction: help me answer this question Find the 4th term in the expansion of (x – 2y)¹², think step by step
### Assistant: In the binomial expansion (a + b)^n, the (r+1)th term is given by Tr+1 = nCran–rbr. Here, a = x, b = -2y, and n = 12. To find the 4th term, we need r = 3. Substituting these values, we get T4 = 12C3 (x)(-2y)³ (x⁻¹)(-2y) = -1344 x y² (2y)⁸. , The answer is The 4th term is -1344 x y² (2y)⁸
