In the binomial expansion of ( cube root of 3 + square root of 2) whole root of 5 find the term which does not contain irrational expression?
If the given expression is
general term in the expansion is
total number of terms = 5+1=6
if the term does not contain irrational terms r/2 must be integer.
r = 0, 2, 4
and
therefore
only for r =2; (5-2)/3 = 3/3 is integer.
thus only one term does not contain irrational expression.
the term which does not contain irrational expression
