To calculate: The expression x1+y1(x+y)1

Expert Solution

Answer to Problem 66E

  x2y2x1+y1=yxxy

Explanation of Solution

Given information:

Given expression is x1+y1(x+y)1

Consider the expression as x1+y1(x+y)1

Now,

  x1+y1(x+y)1=1x+1y1(x+y)=y+xxy1(x+y)=(y+x)(x+y)xy=(x+y)2xy

Therefore, simplest form of the expression x1+y1(x+y)1=(x+y)2xy
