Math Problem Statement

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

Solution

The equation given is:

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

Let's solve it step-by-step:

  1. Simplify (103)0(10^{-3})^0: (103)0=1(10^{-3})^0 = 1

  2. Apply the property of logarithms logabc=clogab\log_a b^c = c\log_a b: logx10002logxx+1=0\log_x 1000 - 2\log_x x + 1 = 0 Recall that logxx=1\log_x x = 1, so: logx100021+1=0\log_x 1000 - 2 \cdot 1 + 1 = 0 Simplifying further: logx10002+1=0logx10001=0\log_x 1000 - 2 + 1 = 0 \quad \Rightarrow \quad \log_x 1000 - 1 = 0

  3. Solving for logx1000=1\log_x 1000 = 1: The equation logx1000=1\log_x 1000 = 1 means that x1=1000x^1 = 1000. Therefore, x=1000x = 1000.

So, the solution to the equation is:

x=1000x = 1000
