The log of a product is the sum of the logs. log a xy = log a x + log a y. …
WebSince the base is e, use the natural logarithm. (If the base were 10, using common logarithms would be better.) ln e 2x = ln 54. 2x = ln 54. Remember that logarithms and exponential functions are inverses. When you have log b b m, the logarithm undoes the exponent, and the result is just m. So ln . e 2x = log e e 2x = 2x. x = Divide both sides ... WebApr 24, 2024 · Different Bases and Different Exponents. The expression b^4 / a^2 is equivalent to (b * b * b * b) / (a * a). Nothing cancels here, but you can transform the expression by grouping by exponents. For …
