It automatically detects the type of problem entered and applies the correct mathematical rules while clearly displaying each solution step.

Whether you are a student learning logarithms, a teacher demonstrating solutions, or someone who needs quick and accurate results, this solver provides clear explanations and reliable answers.

How to Use

1. Enter a logarithmic expression or equation in the input box
   (Examples are shown below)

2. Click the “Solve” button

3. View the step-by-step solution

   • Each step explains the rule or method used

   • The final answer is highlighted clearly

Supported Problem Types

✅ Basic Logarithm Evaluation

log(100)

log2(16)

log4(64)

✅ Simple Logarithmic Equations

log(x) = 3

log2(x) = 5

log(x + 2) = 1

✅ Logarithmic Laws & Simplification

log(a) + log(b)

log(6) − log(7)

3log(x)

log(x*y^2)

✅ Different Bases

log3(81)

log5(x) = 2

log2(3x) = 4

✅ Advanced Logarithmic Equations

log(x) + log(x − 1) = 2

log2(x) + log2(x − 3) = 4

✅ Quadratic Equations in Logarithms

log2(x)^2 − 5*log2(x) + 6 = 0

✅ Nested Logarithms

log2(log10(x)) = 1

Important Notes

• Logarithm bases must be positive and not equal to 1

• Logarithm arguments must be greater than 0

• Mixed-base expressions (e.g. log2(x) + log3(x)) cannot be combined directly

• Some complex problems may require numerical methods or special analysis

The solver will notify you if an equation type is not yet supported.

Who Can Use This Tool?

• Students studying algebra and logarithms

• Teachers demonstrating step-by-step solutions

• Self-learners practicing logarithmic equations

• Anyone needing fast and accurate log calculations

Input Tips (For Best Results)

• Use log(x) for base-10 logarithms

• Use log2(x), log3(x) etc. for other bases

• Use ^ for powers (example: x^2)

• Use * for multiplication (example: 5*log2(x))
