Problem:
Which of the following equations does not have a solution?
Answer Choices:
A. (x+7)2=0
B. β£β3xβ£+5=0
C. βxββ2=0
D. xββ8=0
E. β£β3xβ£β4=0
Solution:
Because β£β3xβ£+5 is strictly positive, the equation (B)β£β3xβ£+5=0β has no solution. The solutions of equations (A), (C), (D), and (E) are β7 , β4,64, and Β±34β, respectively.
