Complete User Guide
Logarithm tab: enter x and base b. Exponentiation tab: calculate b^p. Solve Equation tab: solve log_b(x) = y for unknown x.
The Mathematical Formula
log_b(x) = ln(x) / ln(b)
log_b(x) = ln(x)/ln(b). Product: log(xy) = log(x)+log(y). Power: log(x^n) = n·log(x). Natural log: ln(e^x) = x.
