Question

What is the least possible value of the expression if two different values from the list, 1, 2, 4, and 8 are substituted in any order for the variables 2 and y? (91-->) (9") = 9 After simplifying the expression on the left, what is the value of z, the power of 9? Enter the value of z in the box. I LT ==​

Answer 1

The least possible value of the expression 91^2 - 9^2 when two different values from the list 1, 2, 4, and 8 are substituted in any order for the variables 2 and y is 72.

Step-by-step explanation:

The given expression is 912 - 92. According to the question, we need to find the least possible value of this expression when any two different values from the list 1, 2, 4, and 8 are substituted in any order for the variables 2 and y.

Let's substitute the smallest values from the list, 1 and 2, in the expression:

912 - 92 = 81 - 9 = 72

Hence, the least possible value of the expression is 72.
