Step 1 Ignore the bases and simply set the exponents equal to each other x 1 9 x 1 9 Step 2 Solve for the variable x 9 1 x 8 x 9 1 x 8 Check We can verify There are two methods for solving exponential equations One method is fairly simple but requires a very special form of the exponential equation The other will work on more complicated exponential equations but can be a little messy at times Let s start off by looking at the simpler method

If an exponential equation has 1 on any one side then we can write it as 1 a 0 for any a For example to solve 5 x 1 we can write it as 5 x 5 0 then we get x 0 To solve an exponential equation using logarithms we can either apply log or apply ln on both sides Related Articles Exponential Form Learn how to solve any exponential equation of the form a b cx d For example solve 6 10 2x 48 The key to solving exponential equations lies in logarithms
Here is how to solve exponential equations Manage the equation using the rule of exponents and some handy theorems in algebra Use the theorem above that we just proved Solve displaystyle frac 1 5 x 1 125 5x 11 125 Making the bases on both sides equal to 5 gives An exponential function represents the relationship between an input and output where we use repeated multiplication on an initial value to get the output for any given input Exponential functions can grow or decay very quickly

Step 1 Take logs of both sides 5 x 13 becomes log 5 x log 13 Step 2 Bring down the power in front of the log The power of x can be written in front of the log so that log 5 x log 13 becomes xlog 5 log 13 Step 3 Solve the resulting equation for x How To Given an exponential equation with the form b S b T bS bT where S and T are algebraic expressions with an unknown solve for the unknown Use the rules of exponents to simplify if necessary so that the resulting equation has the form b S b T bS bT Use the one to one property to set the exponents equal
