Question

Find the number of terms in following :

( 2x 3y )19( 1 x2 2x )10

Answer 1

$\huge{Hey Mate!!!}$

☆☞ Here is ur answer ☜☆

☆☞ The number of terms in the expansion of (a + b)n is n + 1.

So, number of terms in the expansion of (2x + 3y)19 = 19 + 1 = 20

 

(1 + x2 + 2x)20 = [(1 + x)2]20 = (1 + x)40

 

So, number of terms in expansion of (1 + x2 + 2x)20  = Number of terms in expansion of (1 + x)40 = 40 + 1 = 41

Answer 2

Heya.....

See here for your answer....

=============

The no of term in given series is...
( a+b )n is n+1

So,, (2x+3y)19 = 19+1 = 20

( 1+x2+2x) 20 = [(1+x)2]=20=(1+x)40

Now,,,

(1+x2+2x)20= no of terms

(1+x)40 = 40+1 = 41 ans...
