Math Problem Statement

x^3logx=100x

Solution

The equation is:

x3logx=100xx^3 \log x = 100x

To solve this, we can approach it step by step:

Step 1: Divide both sides by xx

As long as x0x \neq 0, we can divide both sides of the equation by xx:

x2logx=100x^2 \log x = 100

Step 2: Isolate logx\log x

Now, isolate logx\log x by dividing both sides by x2x^2:

logx=100x2\log x = \frac{100}{x^2}

Step 3: Solve using numerical methods

This is a transcendental equation and doesn’t have an algebraic solution. We can solve it numerically to find the value of xx by plotting or using numerical approximation techniques like Newton's method.

Would you like me to calculate an approximate numerical solution for xx?
