Question

Quizplus · Accepted Answer

The exclamation mark in mathematics means factorial. Therefore, 2! means 2x1=2. The negative sign in option A) makes it impossible for the answer to be 86. Option D) is also incorrect as there is no clear mathematical operation or information provided to arrive at an answer of 8. Option C), on the other hand, is a clear mathematical operation that can be evaluated as 5x6=30x2=60+0= 56. Therefore, the best choice is C) 56. The exclamation mark in mathematics means factorials, which is the product of all positive integers from 1 to the given number. In this case, 86! is an incredibly large number, much larger than any of the other options. Therefore, the only reasonable answer is C, which is 56.
