Consider the expression (a + b)n. according to the binomial theorem, the kth term in the expanded form of this expression (where k≤ n) is a) c(n, k)*xkyn-k b) c(n, k-1)*xkyn-k c) c(n-1, k)*xkyn-k d) c(n-1, k-1)*xkyn-k

The Given expression is

There are (n+1) terms in above expression.

To find the k-th term in the expression , we will evaluate (k+1)-th term.

⇒If the expression is of the form,

Then k-th term is given by

Option A

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
