*individual rational terms*in the

**multinomial**expansion of each of the following expressions:

(I) (√12 + √32 + √48 + √50)

^{6}

(II) (√12 + √32 + √48 + √50)

^{8}

Hence or otherwise, determine the total number of individual rational terms in the multinomial expansion of (√12 + √32 + √48 + √50)

^{2n}in terms of n, whenever n is a positive integer.
