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

MAVERICK [17]

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:

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

Please help me:(*********

Licemer1 [7]

Answer:

x = 16

Step-by-step explanation:

I could be wrong so sorry in advance lol but this is what I did:

I made the equation 3x + 3 = ((7x-10)/2)

I divided the 2nd equation by 2 so that it would be the same length as RZ.

after that, I got: 3x + 3 = 3.5x - 5

from there, i did basic algebra to get the answer 16

hope this helps!
