Question

The number of distinct term in the expansion of (a+b)^4​

Answer 1

Answer:no of distinct terms=5

Step-by-step explanation:

Formula for finding distinct terms

n=(p+k-1) C(k-1) OR

n=((p+k-1)!) / (p! (k-1)!)

p=power k= number of variables

Here p=4 and k=2(a, b are 2 variables)

n=((4+1)!) /(4! *2!) =5! /4! =5

No of distinct terms=5
