Answer to Problem 22WE

The simplification of term that containing x2 is 84x2y5 .

Explanation of Solution

Given information:

Expression:

  (2xy)7

Term:

  x2

Formula used:

Binomial theorem:

  (a+b)n=i=0n(ni)a(ni)bi

Where,

  a= first term

  b= second term

Calculation:

Consider expression (2xy)7

Apply the binomial theorem for (2xy)7

  (a+b)n=i=0n(ni)a(ni)bi

Where,

  a=2x,b=y

So, the simplification are as follows,

  (a+b)n=i=0n(ni)a(ni)bi=i=07(7i)2x(7i)(y)i

The expand summation are as follows:

  =7!0!(70)!(2x)7(y)0+7!1!(71)!(2x)6(y)1+......+7!7!(77)!(2x)0(y)7

The term that contains the x2 is the sixth term,

  7!7!(77)!(2x)2(y)57!7!(77)!=422!=422!(2x)2(y)5(2x)2=22x2=22422!x2(y)5(y)5=y5=22422!x2(y)5

Remove parentheses:

  (a)=a=422!22x2y5

Multiply fractions:

  abc=abc4222x2y52!4222x2y5=168x2y5=168x2y52!2!=2=168x2y52!

Divide the numbers:

  1682=84=84x2y5

The answer of term that containing the x2 is 84x2y5 .
