For integers π, π and π, what would be the minimum and maximum values respectively of π + π + π if log |π| + log |π| + log |π| = 0?
Correct Answer :
-3 and 3
Solution :
The correct option is -3 and 3.
To find the minimum and maximum values of the sum π + π + π, let us analyze the given equation:
Using the logarithmic property log(x) + log(y) + log(z) = log(x Β· y Β· z), we can combine the terms:
By taking the exponential of both sides (with respect to the base of the logarithm, typically 10 or e), we get:
Since π, π, and π are restricted to be integers, their absolute values |π|, |π|, and |π| must also be integers. The only way the product of three positive integers is equal to 1 is if each individual integer has an absolute value of 1.
Therefore, we must have:
This implies that each of the variables π, π, and π can independently take the values of either -1 or 1:
Now, we find the range of values for the sum π + π + π:
1. Minimum Value: The sum is minimized when all three variables are chosen to be their smallest possible value, which is -1.
2. Maximum Value: The sum is maximized when all three variables are chosen to be their largest possible value, which is 1.
Thus, the minimum and maximum values of π + π + π are -3 and 3, respectively.
