Which learning problem is most likely to occur if students internalize the "fruit salad" approach to simplifying expressions?
a. Students will tend to cojoin terms in an expression like 3x + 4 = 7x
b. Students will simplify an expression like 2m + 3 to 5m
c. Students will believe that (2x)(4y) does not equal 8xy because 2x and 4y are not like terms
d. Students will not be able to graph the equation y = 2x + 3 without the assistance of a graphing calculator
Ans: c
