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

It's A on edge.

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 equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
