Math Problem Statement

log_x 1000 - log_x x^2 + (10^{-3})^0 = 0

Solution

The equation provided in the image is:

logx1000logxx2+(103)0=0\log_x 1000 - \log_x x^2 + (10^{-3})^0 = 0

Let’s solve this step by step:

Step 1: Simplify the exponent and constant terms

(103)0=1(10^{-3})^0 = 1 because any non-zero number raised to the power of 0 is 1.

This simplifies the equation to: logx1000logxx2+1=0\log_x 1000 - \log_x x^2 + 1 = 0

Step 2: Apply logarithmic properties

Using the logarithmic property: logxalogxb=logx(ab)\log_x a - \log_x b = \log_x \left(\frac{a}{b}\right)

We can simplify the equation: logx(1000x2)+1=0\log_x \left(\frac{1000}{x^2}\right) + 1 = 0

Step 3: Move the constant term

Now, subtract 1 from both sides: logx(1000x2)=1\log_x \left(\frac{1000}{x^2}\right) = -1

Step 4: Convert the logarithmic equation to exponential form

Using the fact that: logxA=B    A=xB\log_x A = B \implies A = x^B

We can rewrite the equation as: 1000x2=x1\frac{1000}{x^2} = x^{-1}

Step 5: Simplify the equation

Multiply both sides of the equation by x2x^2 to eliminate the fraction: 1000=x1000 = x

Step 6: Final solution

Thus, the value of xx is: x=1000x = 1000

Final Answer:

The solution to the equation is x=1000x = 1000.
