Q64.If the ratio of the fifth term from the beginning to the fifth term from the end in the expansion of 4√2 + 4 1 is √3 √6: 1, then the third term from the beginning is: (1) 30√2 (2) 30√3 (3) 60√2 (4) 60√3
What This Question Tests
The question involves finding the value of 'n' using the given ratio of terms from the beginning and end of a binomial expansion, and then calculating a specific term of the expansion.
Concepts Tested
Formulas Used
Tr+1 = nCr * a^(n-r) * b^r
r-th term from end is (n-r+2)-th term from beginning
