WebFunctions - Exponential Functions Objective: Solve exponential equations by ﬁnding a common base. As our study of algebra gets more advanced we begin to study more involved functions. One pair of inverse functions we will look at are exponential functions and logarithmic functions. Here we will look at exponential functions and then we WebExample. Solve 5x+2 =4x 5 x + 2 = 4 x. In general we can solve exponential equations whose terms do not have like bases in the following way: Apply the logarithm to both sides of the equation. If one of the terms in the equation has base 10 10, use the common logarithm. If none of the terms in the equation has base 10 10, use the natural logarithm. WebIf we are given equations involving exponentials or the natural logarithm, remember that you can take the exponential of both sides of the equation to get rid of the logarithm or take the natural logarithm of both sides to get rid of the exponential. Example. Solve 0.5 = e x. Then ln (0.5) = ln (e x) ln (0.5) = x. greaterairport.sacompplan.com
