1-84.

Though many students think the following statements are true, each of them is actually FALSE. Confirm this by substituting simple numbers for the variables and doing the arithmetic. Note: Do not use 0 or 1; they are too special. Homework Help ✎

**REMEMBER: EACH OF THESE STATEMENTS IS FALSE.**(

*x*+*y*)^{2}=*x*^{2}+*y*^{2}= *p*+*q*3

*w*^{−}^{2}=(

*a*^{−}^{1}+*b*^{−}^{1})^{−1}=*a*+*b*3 · 2

= 6^{x}^{x}

Try substituting numbers such as 2, 3, 4, or 5.
