Answer 2

the value is 1.5

Step-by-step explanation:

Given : Equation x=\frac{\log 125}{\log 25}x=log25log125

To find : Solve for x ?

Solution :

x=\frac{\log 125}{\log 25}x=log25log125

Re-write 125 and 25 as power of 5,

x=\frac{\log 5^3}{\log 5^2}x=log52log53

Applying logarithmic property, \log a^x=x\log alogax=xloga

x=\frac{3\log 5}{2\log 5}x=2log53log5

Solve it,

x=\frac{3}{2}x=23

x=1.5x=1.5

Therefore, the value of x is 1.5.
