It doesn't matter what base of the logarithm to use.Solving exponential equations using logarithms Solve exponential equations using logarithms: base-10 and base-e Solving exponential equations using logarithms: base-2 …

Using Like Bases to Solve Exponential Equations . The first technique involves two functions with like bases. Recall that the one-to-one property of exponential functions tells us that, for any real numbers b, S, and T, where b>0, S>0, b≠1, b ≠1, b S =b T if and only if S=T.. In other words, when an exponential equation has the same base on each side, the exponents must be equal.

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 …

The key to solving exponential equations lies in logarithms! Let's take a closer look by working through some examples. Solving exponential equations of the form a ⋅ b x = d Let's solve 5 ⋅ 2 x = 240 . To solve for x , we must first isolate the exponential part. To do this, divide both sides by 5 as shown below.

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) log (a) = log (b) is equivalent to a = b, a = b, we may apply logarithms with the same base on both sides of an ...We can use any logarithm and the natural logarithm and common logarithm are usually good choices since most calculators can handle them. In this case one of the bases is a 10 and so the common logarithm is probably the better choice. Taking the logarithm (using the common logarithm) of both sides gives,

9 years ago. 1st Isolate the base with the exponent by dividing both sides by 5 and you get: 10^x-31=16.32. 2nd log both sides. log 10 of 10^x-31=log 10 of 16.32. The log 10 and 10 cancel out, your left with: x-31=log 10 of 16.32. 3rd add 31 to both sides to isolate x. …

Solve Logarithmic Equations Using the Properties of Logarithms. In the section on logarithmic functions, we solved some equations by rewriting the equation in exponential form. Now that we have the properties of logarithms, we have additional methods we can use to solve logarithmic equations.For example, we define 51/3 to be the cube root of 5 because we want (51/3) 3 = 5(1/3)3 to hold, so (51/3) 3 must equal 5. N.RN.A.2. Rewrite expressions involving radicals and rational exponents using the properties of exponents. Includes expressions with variable factors, such as the cubic root of 27x5y3.Now that we have looked at a couple of examples of solving exponential equations with different bases, let’s list the steps for solving exponential equations that have different bases.
