Introduction

In a scientific experiment, understanding the growth of bacteria is crucial for various applications, including medicine and food safety. The number of bacteria in an experiment can be represented by a function, which in this case is $f(x) = 4^x$ , where $x$ represents the number of hours. This function indicates that the number of bacteria doubles every hour. In this article, we will solve for $x$ when $f(x) = 64$ , which represents the number of bacteria after a certain number of hours.

Understanding the Function

The function $f(x) = 4^x$ is an exponential function, where the base is 4 and the exponent is $x$ . This means that for every increase in $x$ by 1, the value of $f(x)$ is multiplied by 4. For example, if $x = 2$ , then $f(x) = 4^2 = 16$ . If $x = 3$ , then $f(x) = 4^3 = 64$ . This function represents the rapid growth of bacteria in the experiment.

Solving for x

To solve for $x$ when $f(x) = 64$ , we need to isolate $x$ in the equation. Since $f(x) = 4^x$ , we can rewrite the equation as $4^x = 64$ . To solve for $x$ , we can use logarithms. Taking the logarithm of both sides of the equation, we get:

\log(4^x) = \log(64)

Using the property of logarithms that $\log(a^b) = b\log(a)$ , we can rewrite the equation as:

x\log(4) = \log(64)

Now, we can solve for $x$ by dividing both sides of the equation by $\log(4)$ :

x = \frac{\log(64)}{\log(4)}

Calculating the Value of x

To calculate the value of $x$ , we need to evaluate the expression $\frac{\log(64)}{\log(4)}$ . Using a calculator, we get:

x = \frac{\log(64)}{\log(4)} \approx \frac{1.806}{0.602} \approx 3

Therefore, when $f(x) = 64$ , the value of $x$ is approximately 3.

Conclusion

In this article, we solved for $x$ when $f(x) = 64$ , which represents the number of bacteria after a certain number of hours in an experiment. We used the function $f(x) = 4^x$ to represent the growth of bacteria and solved for $x$ using logarithms. The value of $x$ is approximately 3, which means that there will be 64 bacteria in the 3rd hour.

Discussion

The result of this calculation has significant implications for the experiment. It indicates that the bacteria will double every hour, and by the 3rd hour, there will be 64 bacteria. This information can be used to predict the growth of bacteria in the experiment and make informed decisions about the experiment's design and execution.
