Math Problem Statement
Solve the equation by using properties of the logarithm function. Enter the value of x rounded to four decimal places. 4×log(7^x)=52
Solution
To solve the equation using the properties of logarithms, follow these steps:
Step 1: Apply the logarithm power rule
The logarithm power rule states that . So, we can rewrite the equation as:
Step 2: Isolate the logarithmic term
Next, divide both sides of the equation by 4 to isolate the term:
Step 3: Solve for
Now, divide both sides of the equation by to solve for :
Step 4: Calculate the value of
Now, compute the value of using a calculator:
So, the value of rounded to four decimal places is .
