Question

Which expression can be used to approximate the expression below,for all positive number a,b and x where a =/ 1 and b=/ 1

Answer 1

Answer:

$log_ax=\frac{log_bx}{log_ba}$

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:$log_ax$

We have a logarithmic property:

$log_my=\frac{log_ny}{log_nm}$    (1)

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

$log_ax=\frac{log_bx}{log_ba}$

Therefore, Option 1st is correct.

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

$log_1x=\frac{log_1x}{log_11}$

Answer 2

Answer:

It's A on edge.
