Answer:
4TH TERM : 1384 (X^6)(Y^4)
Step-by-step explanation:
*************** HEY DEAR ****************
HERE IS YOUR ANSWER........
AS WE KNOW IN BINOMIAL SERIES...
4TH TERM OF SERIES = nC4 (2x)^(n-r) (-y)^r
SO,
HERE ALSO.......
4TH TERM => 10C4 (2X)^6 (-Y)^4 ...............................(1.)
10C4 => 10*9*8*7 /(4*3*2*1) => 210
PUT VALUE IN EQUATION (1.)
SO ,
4TH TERM => 210 (64)(X^6)(Y^4)
=> 1384 (X^6)(Y^4)
