Solving for 1/x - 1/y in the Equation (2.3)^x = (0.23)^y = 1000
This problem involves working with exponential equations and manipulating them to find a solution. Let's break down the steps to find the value of 1/x - 1/y:
1. Expressing the Equations in a Common Base:
We can express all the numbers in the equations using a common base. Since 2.3 and 0.23 are related, let's use base 2.3:
- (2.3)^x = 1000
- (0.23)^y = 1000
- (2.3)^(-y) = 1000 (Since 0.23 = 2.3^-1)
Now we have:
- (2.3)^x = 1000
- (2.3)^(-y) = 1000
2. Equating Exponents:
Since both equations equal 1000, the exponents must be equal:
- x = -y
3. Finding 1/x - 1/y:
Let's substitute -y for x in the expression 1/x - 1/y:
1/x - 1/y = 1/(-y) - 1/y = -1/y - 1/y = -2/y
Therefore, the value of 1/x - 1/y is -2/y. Note that we cannot determine the exact numerical value without knowing the value of y.
