Question #86d11

Answer 1

Refer to explanation

Explanation:

The Pascal triangle is as follows

Now we see the fifth row because we expand `(1+x)^5` hence

we have that the binomial coefficients of the expansion according to Pascal Triangle are

#(1+x)^5=1^5+5*1^4*x+10*1^3*x^2+10*1^2*x^3+5*1*x^4+1*x^5=> (1+x)^5=1+5x+10x^2+10x^3+5x^4+x^5#
