Chapter 6.6, Problem 60E

To determine

To calculate: .The equation for the value of $x$ .

Answer to Problem 60E

The required value of $x$ is $1.233$ .

Explanation of Solution

Given Information:

The given equation is $\log x=7^{-x}$ .

Calculation:

Consider the equation is $\log x=7^{-x}$ .

Solve by Graphically:

Let $y=\log x$ and $y=7^{-x}$ .

Graph for both equation.

From the graph it is clearly seen that the value of $x$ is $1.233$ .

Thus, the solution is $x=1.233$ .

Hence, the required value of $x$ is $x=1.233$ .
