To solve exponential equations without logarithms, you need to have equations with comparable exponential expressions on either side of the "equals" sign, so you can compare the powers and solve. In other words, you have to have " (some base) to (some power) equals (the same base) to (some other power)", where you set the two powers equal to ...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. Write a new equation that sets the bases equal to each other. x = 3 x = 3. x = 6. Explanation: We need to make the bases equal before attempting to solve for x. Since 16 = 42 we can rewrite our equation as. 42x = 422x−6. Remember: the exponent rule (xn)m = xn⋅m. 42x = 42(2x−6) Now that our bases are equal, we can set the exponents equal to each other and solve for x . 2x = 2(2x − 6)Exercise 68. Exercise 69.

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.

Review ...Rewriting Equations So All Powers Have the Same Base. Sometimes the common base for an exponential equation is not explicitly shown. In these cases, we can sometimes rewrite the terms in the equation as powers with a common base, and solve using the one-to-one property.which of the following is its projected population in 10 years? Show the exponential model you use to solve this problem. (1) 9,230 (2) 76 (3) 18,503 (4) ,310 The stock price of Windpowerlnc is increas@g at a rate of 4% er week. Its initial value was SZQper share. On the other hand, the stock price in GerbilEnergy is crashing (losing value) at Working Together. Exponents and Logarithms work well together because they "undo" each other (so long as the base "a" is the same): They are "Inverse Functions". Doing one, then the other, gets us back to where we started: Doing ax then loga gives us back x: loga(ax) = x. Doing loga then ax gives us back x: aloga(x) = x.Then, take the logarithm of both sides of the equation to convert the exponential equation into a logarithmic equation. The logarithm must have the same base as the exponential expression in the equation. Use logarithmic properties to simplify the logarithmic equation, and solve for the variable by isolating it on one side of the equation.when doing math problems, it is best to not round until you reach the final answer. if you are using a calculator to find the logs you used in the change of base formula, you can simply use the fraction function and then type in the logs to find the answer, rather than taking a rounded number of each and calculating with them.
