Math Problem Statement

logx​1000−logx​x2+(10−3)0=0

Solution

Let's solve the equation:

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

Step 1: Simplify the components

  1. Logarithmic terms:

    • logx1000\log_x 1000 stays as it is for now.
    • logxx2=2\log_x x^2 = 2, since the logarithm of a power simplifies as logbbk=k\log_b b^k = k.
  2. Constant term:

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

Now the equation becomes:

logx10002+1=0\log_x 1000 - 2 + 1 = 0

Step 2: Simplify the equation

logx10001=0\log_x 1000 - 1 = 0

Step 3: Solve for logx1000\log_x 1000

logx1000=1\log_x 1000 = 1

This means that x1=1000x^1 = 1000, or simply:

x=1000x = 1000

Final Answer:

The solution is x=1000x = 1000.
