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:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
