Math Problem Statement

Solve for x: log_3(x^5) = -1

Solution

To solve the equation:

log3(x5)=1\log_3(x^5) = -1

we need to convert this logarithmic equation into an exponential form. Here's the step-by-step solution:

Step 1: Rewrite the Logarithmic Equation

The equation log3(x5)=1\log_3(x^5) = -1 implies: x5=31x^5 = 3^{-1}

Step 2: Simplify the Right Side

Since 31=133^{-1} = \frac{1}{3}, we get: x5=13x^5 = \frac{1}{3}

Step 3: Take the Fifth Root

To solve for xx, take the fifth root of both sides: x=(13)15x = \left(\frac{1}{3}\right)^{\frac{1}{5}}

Step 4: Simplify Further

This expression can be simplified further, or you can calculate its approximate decimal value: x0.8660x \approx 0.8660

So, the solution is: x0.8660x \approx 0.8660
