Used more than 3 operations
Parentheses affected the value
Used at least (1) number greater than 9
Used exponents
a) 0
b) 1
c) 2
d) 3

Answer 1

An example satisfying the criteria for scoring 4 difficulty points in the student's question is (10 + 2)² × (3 + 2), as it uses more than three operations, parentheses that affect the value, at least one number greater than 9, and exponents.

Step-by-step explanation:

The student's question revolves around calculating a difficulty score for an expression based on several criteria. To score points, the expression must contain more than three operations, have parentheses that affect the value, include at least one number greater than 9, and use exponents.

An example satisfying these requirements could be (10 + 2)² × (3 + 2). This expression has more than three operations (addition, exponentiation, and multiplication), uses parentheses which affect the value, includes a number greater than 9, and uses an exponent. Thus, by satisfying all the listed criteria, it would score a difficulty of 4 points.
