Now try Exercise 97. Sometimes it is necessary to rationalize the numerator of an expression. 5 you will use the technique shown in the next example to rationalize the numerator of an expression from calculus. WARNING / CAUTION Do not confuse the expression Ί5 ϩ Ί7 with the expression Ί5 ϩ 7. In general, Ίx ϩ y does not equal Ίx ϩ Ίy. Similarly, Ίx 2 ϩ y 2 does not equal x ϩ y.
