Solve the resulting equation,Here is the definition of the logarithm function. If b b is any number such that b > 0 b > 0 and b ≠ 1 b ≠ 1 and x >0 x > 0 then, We usually read this as “log base b b of x x ”. In this definition y =logbx y = log b x is called the logarithm form and by = x b y = x is called the exponential form.By establishing the relationship between exponential and logarithmic functions, we can now solve basic logarithmic and exponential equations by rewriting. Example. Solve log 4 ( x) = 2 for x. Solution. By rewriting this expression as an exponential, 4 2 = x, so x = 16. Example. Solve 2 x = 10 for x. Solution.Solve 3ex + 2 = 24. Find the exact answer and then approximate it to three decimal places. 3 e x + 2 = 24. Isolate the exponential by dividing both sides by 3. e x + 2 = 8. Take the natural logarithm of both sides. ln e x + 2 = ln 8. Use the Power Property to get the x as a factor, not an exponent. ( x + 2) ln e = ln 8.Another strategy to use to solve logarithmic equations is to condense sums or differences into a single logarithm. Example 12.6.2. Solve: log3x + log3(x − 8) = 2. Solution: log3x + log3(x − 8) = 2. Use the Product Property, logaM + logaN = logaM ⋅ N. log3x(x − 8) = 2. Rewrite in exponential form.As with exponential equations, we can use the one-to-one property to solve logarithmic equations. The one-to-one property of logarithmic functions tells us that, for any real numbers x > 0, S > 0, T > 0 and any positive real number b, where b ≠ 1 b ≠ 1, logbS= logbT if and only if S = T l o g b S = l o g b T if and only if S = T.Here is a set of practice problems to accompany the Solving Logarithm Equations section of the Exponential and Logarithm Functions chapter of the notes for ...
In addition, we discuss how to evaluate some basic logarithms including the use of the change of base formula.
