Solve exponential equation using log
WebMar 28, 2014 · Since we're dealing with variables as indices (aka powers, exponents), log_10, log_(anything), and ln (the natural log) all work because they are inverses of exponential functions. By using … WebOct 31, 2024 · Solve 3ex + 2 = 24. Find the exact answer and then approximate it to three decimal places. 3 e x + 2 = 24. Isolate the exponential by dividing both sides by 3. e x + 2 = 8. Take the natural logarithm of both sides. ln e x + 2 = ln 8. Use the Power Property to get the x as a factor, not an exponent. ( x + 2) ln e = ln 8.

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) Web1st step. All steps. Final answer. Step 1/1. Give by-. Take the natural logarithm of both sides of the equation to remove the variable from the exponent. ln ( 7 x) = ln ( 5) Expand ln ( 7 x) by moving x outside the logarithm.
