Positive integers are numbers greater than zero. Which of the following expressions results in the largest positive number?
Correct answer
C
Rationale
To find the largest positive number among the expressions, we evaluate each one:
A) (2 + 3)^2 = 5^2 = 25
B) 5 x 7 + 2 = 35 + 2 = 37
C) 10^2 - 4^2 = 100 - 16 = 84
D) (8 - 1) x 3 = 7 x 3 = 21
Therefore, the expression that results in the largest positive number is 10^2 - 4^2, which equals 84. Choices A, B, and D result in smaller numbers.
