Which expression can be used to approximate the expression below, for all positive numbers a, b, and x, where a Not-equals 1 and b Not-equals 1? logax

Therefore, Option 1st is correct.

Step-by-step explanation:

We have given that a=1 and b=1

We need to find expression equivalent to the given expression

We have:

We have a logarithmic property:

   (1)

Here, we have m=a, x=y and n=b on substituting the values in (1) we get:

Therefore, Option 1st is correct.

And when a=1 and b=1 we get:
