The mathematical expression for x is is fewer than 9 is x< 9
Since we have to divide 60 by ¾, so get 60/ ¾ =60* 4/3 = 80
The statement <span>The coefficient of x^k y^n-k in the expansion of (x+y)^n equals (n-k / k) is true. This will show the standard formula and the expansion of it. We all know that it can still be expanded based on the power or degree of the terms.</span>
