xlogx11logx4+logx30.25+x=3
x=?
To solve this problem, we'll follow these steps:
- Step 1: Simplify the logarithmic expression logx4+logx30.25.
- Step 2: Use the change of base formula for logarithms.
- Step 3: Substitute and solve for x.
Now, let's work through each step:
Step 1: Simplify the logarithmic expression by using the property logx4+logx30.25=logx(4×30.25).
Step 2: Calculate 4×30.25=121, then express as logx121.
Step 3: The equation becomes xlogx11logx121+x=3. We know logx121=2 when x=11, thus evaluate the expression with possible values.
Consider a simpler value for x, like 2. calc log24=2 and log2121. Using the logarithmic laws further simplifies if appropriate, achieving solution x=2.
Therefore, the solution to the problem is x=2.
