WebThe key to solving exponential equations lies in logarithms! Let's take a closer look by working through some examples. Solving exponential equations of the form a\cdot b^x=d a ⋅ bx = d Let's solve 5\cdot 2^x=240 5 ⋅2x = 240. To solve for x x, we must first isolate the exponential part. To do this, divide both sides by 5 5 as shown below. WebJul 9, 2024 · The domain of logx is x>1 but when it comes to loglog (x) the function is defined when logx>0 which implies that x>e^0 or a^0 =1.
