Answer

So, the expanded form of the given logarithmic expression is 2log(x)+log(z)

Steps

Step 1 :Given the logarithmic expression log(zx2)

Step 2 :Using the properties of logarithms, we can expand this expression. The property log(ab)=log(a)+log(b) allows us to separate the variables z and x2

Step 3 :So, log(zx2)=log(x2)+log(z)

Step 4 :We still have an exponent in the term log(x2). We can use the property log(an)=nlog(a) to remove this exponent

Step 5 :Applying this property, we get 2log(x)+log(z)

Step 6 :So, the expanded form of the given logarithmic expression is 2log(x)+log(z)
