How to solve Exponential Equations
We have studied many maths activities about the laws of indices, the zero index, negative and fractional indices. Finally we will use our understanding of indices to solve exponential equations. When you are revising for maths and solve past paper questions, you will probably already have encountered exponential equations. First of all it is important to understand what an exponential equation is. An exponential equation is an equation where x (the variable) is in the exponent (index). If you graph an exponential function (this I will explain in another section) you will get a graph looking similar to the one on the picture next to this text. When you look at the first video I will explain to you step by step how to solve exponential functions. Then you can try to solve the example maths questions of the second maths video. Please like and share these videos if they were useful so also your friends will pass their GCSE IGCSE maths exam. Let me know on Facebook or Twitter or on the forum on the homepage of this site if you still don't understand how to solve exponential equations. Then I will make some more videos for you. Thanks and good luck!
