Solving exponential equations using logarithms common core algebra 2 homework.

In this course students study a variety of advanced algebraic topics including advanced factoring, polynomial and rational expressions, complex fractions, and binomial expansions. Extensive work is done with exponential and logarithmic functions, including work with logarithm laws and the solution of exponential equations using logarithms.Solving Exponential Equations Using Logarithms. Sometimes the terms of an exponential equation cannot be rewritten with a common base. In these cases, we solve by taking the logarithm of each side. Recall, since \(\log(a)=\log(b)\) is equivalent to \(a=b\), we may apply logarithms with the same base on both sides of an exponential equation.This is called logarithmic differentiation. It's easiest to see how this works in an example. Example 1 Differentiate the function. y = x5 (1−10x)√x2 +2 y = x 5 ( 1 − 10 x) x 2 + 2. Show Solution. So, as the first example has shown we can use logarithmic differentiation to avoid using the product rule and/or quotient rule.We can then conclude that if 3x =32 then x =2. This is the process we will use to solve exponential functions. If we can re-write a problem so the bases match, then the exponents must also match.

So far, the only thing we've really been able to use algebraically to solve an exponential equation is the method of common basis. You remember that a few lessons ago where we wrote each side of the equation with the same base and then set the exponents equal.

Solution. (x + 4)8 = 78 ( x + 4) 8 = 7 8. Again, you have two exponential expressions that are equal to each other. In this case, both sides have the same exponent, and this means the bases must be equal. x + 4 = 7 x + 4 = 7.
