Question

does 2 log(base5)x+1/2log(base5)y-4log(base5)z=log(base5) x^2sqrt/z^4. What properties did you use in making decision.

Answer 1

what log rules are you already familiar with?

Answer 2

I am having lots of trouble with these:( I know change of base.

Answer 3

And that if logbx=logby that x=y

Answer 4

this requires just the basic log rules

Answer 5

have a look here to see these basic rules: http://www.purplemath.com/modules/logrules.htm

Answer 6

if you are still stuck after this, then let me know and I will try and guide you further.

Answer 7

so maybe I am overthinking it? I am just really confused by this..going now to purple math

Answer 8

After reading I think that this equation is true, am I correct?

Answer 9

it is, but I believe you missed a 'y' in the right-hand-side of the equals sign (inside the sqrt)

Answer 10

What happened to the "y" term?

Answer 11

You are correct, I did

Answer 12

the main point here is do you know how to get to this answer?

Answer 13

Yes because they are all log base 5 so then use the properties to see what the other side would equal :)

Answer 14

ok - thats good. :)

Answer 15

Thank you

Answer 16
