Chapter 12: Problem 118

Explain how to solve an exponential equation when both sides can be written as a power of the same base.

Short Answer

Expert verified
To solve an exponential equation where both sides have the same base, rewrite both sides so that they are expressed as powers of this base, set the exponents equal to each other, and then solve the resulting equation.

Step by step solution

01

Express Both Sides as Powers of the Same Base

To begin, it is important to express both sides of the given equation as powers of the same base. Identify the common base that both terms of the equation can be raised to in order to express them equivalently. If the base terms of the equation are not the same, seek a way to rewrite them in terms of a common base.
02

Setting the Exponents Equal to Each Other

Once both sides of the equation are expressed as powers of the same base, it can be concluded that the exponents must be equal to each other for the entire equation to hold true. This stems from the fundamental rule of exponents stating that if a^m = a^n, then m must equal n.
03

Solve the Resulting Equation

With the exponents now set equal to each other, what remains is a simpler equation to solve. Standard methods of solving equations, like isolating variables and simplifying, can now be used. Finding the value of the variable in this step gives the answer of the original equation.

The function $$N(t)=\frac{30,000}{1+20 e^{-1.5 t}}$$ describes the number of people, \(N(t),\) who become ill with influenza \(t\) weeks after its initial outbreak in a town with \(30,000\) inhabitants. The horizontal asymptote in the graph indicates that there is a limit to the epidemic's growth. (GRAPH CAN'T COPY) a. How many people became ill with the flu when the epidemic began? (When the epidemic began, \(t=0\).) b. How many people were ill by the end of the third week? c. Why can't the spread of an epidemic simply grow indefinitely? What does the horizontal asymptote shown in the graph indicate about the limiting size of the population that becomes ill?

What is an exponential equation?

The pH scale is used to measure the acidity or alkalinity of a solution. The scale ranges from 0 to \(14 .\) A neutral solution, such as pure water, has a pH of 7. An acid solution has a pH less than 7 and an alkaline solution has a p \(H\) greater than \(7 .\) The lower the \(p H\) below \(7,\) the more acidic is the solution. Each whole-number decrease in \(p H\) represents a tenfold increase in acidity. The \(p H\) of a solution is given by $$\mathrm{pH}=-\log x$$ where \(x\) represents the concentration of the hydrogen ions in the solution, in moles per liter. Use the formula to solve. Express answers as powers of \(10 .\) a. The figure indicates that lemon juice has a \(\mathrm{pH}\) of \(2.3 .\) What is the hydrogen ion concentration? b. Stomach acid has a pH that ranges from 1 to 3. What is the hydrogen ion concentration of the most acidic stomach? c. How many times greater is the hydrogen ion concentration of the acidic stomach in part (b) than the lemon juice in part (a)?
