Solutions

Chapter 1.3, Problem 54E
To determine

To calculate: The simplified value of the expression (x12+y12)(x12y12) .

Expert Solution

Answer to Problem 54E

The value of the expression (x12+y12)(x12y12) is xy .

Explanation of Solution

Given information:

The expression (x12+y12)(x12y12) .

Formula used:

The special product formula of difference of squares to multiply the algebraic expressions is mathematically expressed as,

  (A+B)(AB)=A2B2

Calculation:

Consider the given expression (x12+y12)(x12y12) .

Recall the special product formula of difference of squares to multiply the algebraic expressions is mathematically expressed as,

  (A+B)(AB)=A2B2

Here, A=x12 and B=y12 .

Apply it,

  (x12+y12)(x12y12)=(x12)2(y12)2=xy

Thus, the value of the expression (x12+y12)(x12y12) is xy .
