Find the sum of all coefficients in the following binomial expansion.

natima [27]

Answer:

We can find the sum of all the coefficients by substituting all the variables in the expansion with one.

a. u=1,v=1

sum= $(2*1+1)^{10}$ = $3^{10}$

b.u=1,v=1

sum= $(2*1-1)^{10}$ =1

c.u=1,v=1

sum= $(2*1-3*1)^{11$ =-1

d.u=1,v=1

sum= $(1-3*1)^{11}$ =- $2^{11$

e.i=1

sum= $(1+1)^{10$ = $2^{10$

f.i=1

sum= $(1-1)^{10$ =0

g.i=1

sum= $(1+1)^{200$ = $2^{200$

h.i=1

sum= $(1+1)^{201}$ = $2^{201$
