Question
If 𝑚log32+2log3𝑚=m log 3 2 +2 log 3 m = 2, then what is the value of 𝑚m ?
Solution 1
To solve for m in the equation mlog3(2) + 2log3(m) = 2, follow these steps:
Step 1: Rewrite the equation using the properties of logarithms.
The equation becomes m*log3(2) + log3(m^2) = 2.
Step 2: Convert the equation to exponential form.
This gives us 3^m * 2 + m^2 = 2.
Step 3: Simplify the equation.
This simplifies to 3^m * 2 + m^2 - 2 = 0.
Step 4: Solve for m.
Unfortunately, this equation cannot be solved algebraically for m. You would need to use numerical methods to find the value of m.
Solution 2
The given equation is 𝑚log32 + 2log3𝑚 = 2.
First, we can simplify this equation using the properties of logarithms.
The property log_b(a^n) = n*log_b(a) allows us to rewrite the equation as:
log3(2^m) + log3(m^2) = 2.
Then, we can use the property log_b(a) + log_b(c) = log_b(a*c) to combine the two logarithms on the left side of the equation:
log3(2^m * m^2) = 2.
This simplifies to:
log3(2^m * m^2) = log3(3^2).
Since the bases and the results of the logarithms are equal, we can set the arguments of the logarithms equal to each other:
2^m * m^2 = 3^2.
Solving this equation gives m = 3.
