Introduction

In mathematics, functions play a crucial role in describing relationships between variables. The functions $f$ and $g$ are given by $f(x)=4^{(5x-1)}$ and $g(x)=8^{(x/4)}$ . When solving the equation $f(x)=g(x)$ , the functions can be rewritten in equivalent forms so that the equation can be solved. In this article, we will explore the functions $f$ and $g$ , and discuss how they can be rewritten to facilitate the solution of the equation.

The Function $f(x)$

The function $f(x)$ is given by $f(x)=4^{(5x-1)}$ . This function can be rewritten in an equivalent form using the properties of exponents. Specifically, we can rewrite $4^{(5x-1)}$ as $(2^2)^{(5x-1)}$ . Using the property of exponents that states $(a^b)^c=a^{bc}$ , we can simplify this expression to $2^{2(5x-1)}$ . This is an equivalent form of the function $f(x)$ .

Simplifying the Function $f(x)$

We can further simplify the function $f(x)$ by evaluating the exponent. Specifically, we can rewrite $2^{2(5x-1)}$ as $2^{10x-2}$ . This is a simplified form of the function $f(x)$ .

The Function $g(x)$

The function $g(x)$ is given by $g(x)=8^{(x/4)}$ . This function can be rewritten in an equivalent form using the properties of exponents. Specifically, we can rewrite $8^{(x/4)}$ as $(2^3)^{(x/4)}$ . Using the property of exponents that states $(a^b)^c=a^{bc}$ , we can simplify this expression to $2^{3(x/4)}$ . This is an equivalent form of the function $g(x)$ .

Simplifying the Function $g(x)$

We can further simplify the function $g(x)$ by evaluating the exponent. Specifically, we can rewrite $2^{3(x/4)}$ as $2^{(3x)/4}$ . This is a simplified form of the function $g(x)$ .

Solving the Equation $f(x)=g(x)$

Now that we have rewritten the functions $f$ and $g$ in equivalent forms, we can solve the equation $f(x)=g(x)$ . Specifically, we can set the two functions equal to each other and solve for $x$ . This gives us the equation $2^{10x-2}=2^{(3x)/4}$ .

Using Properties of Exponents to Solve the Equation

We can use the properties of exponents to solve the equation $2^{10x-2}=2^{(3x)/4}$ . Specifically, we can equate the exponents and solve for $x$ . This gives us the equation $10x-2=(3x)/4$ .

Solving for $x$

We can solve for $x$ by isolating the variable on one side of the equation. Specifically, we can multiply both sides of the equation by 4 to eliminate the fraction. This gives us the equation $40x-8=3x$ . We can then add 8 to both sides of the equation to get $40x=3x+8$ . Finally, we can subtract $3x$ from both sides of the equation to get $37x=8$ . Dividing both sides of the equation by 37 gives us the solution $x=8/37$ .

Conclusion

In this article, we explored the functions $f$ and $g$ , and discussed how they can be rewritten in equivalent forms to facilitate the solution of the equation $f(x)=g(x)$ . We showed that the functions $f$ and $g$ can be rewritten as $f(x)=2^{10x-2}$ and $g(x)=2^{(3x)/4}$ , respectively. We then used the properties of exponents to solve the equation $f(x)=g(x)$ , and found the solution to be $x=8/37$ . This demonstrates the importance of using equivalent forms of functions to solve equations in mathematics.

Introduction

In our previous article, we explored the functions $f$ and $g$ , and discussed how they can be rewritten in equivalent forms to facilitate the solution of the equation $f(x)=g(x)$ .
