Find out the value of n element of a set, Mathematics

Assignment Help:

A set consists of (2n+1) elements. If the number of subsets of this set which consist of at most n elements is 8192. Find out the value of n.

Ans: The following set has (2n + 1) elements. The number of subsets of this set comprising at the most n elements is following by formula

2n + 1C0 + 2n + 1C1 + 2n + 1C2 + ..... 2n + 1Cn = (1/2)22n+1 =2 2n

This figure is given to be 8192, so 22n = 8192 ⇔ 22n = 213 ⇔ 2n = 13 ⇔ n = 6.5

 Hence n = 6.5.
