WebWe can use logarithms to solve *any* exponential equation of the form a⋅bᶜˣ=d. For example, this is how you can solve 3⋅10²ˣ=7: 1. Divide by 3: 10²ˣ=7/3. 2. Use the definition of logarithm: 2x=log (7/3) 3. Divide by 2: x=log (7/3)/2 Now you can use a calculator to find the solution of the equation as a rounded decimal number. WebAn exponential equation is an equation with exponents where the exponent (or) a part of the exponent is a variable.For example, 3 x = 81, 5 x - 3 = 625, 6 2y - 7 = 121, etc are some examples of exponential equations. We may come across the use of exponential equations when we are solving the problems of algebra, compound interest, exponential growth, …
WebThe natural log would have given the same answer (eventually, after some manipulation), but the base-10 log will be simpler in this case: 1000 0.12 x = 25,000 log(1000 0.12 x ) = log(25,000)
WebJul 9, 2024 · Take the log of both sides. You can take any log you want, but remember that you actually need to solve the equation with this log, so you should use common or natural logs only. Using the common log on both sides gives you log 4 3x –1 = log 11. Use the power rule to drop down the exponent.
