what can one be rewritten as?

2log5(x) can be written as log5(x^2)

then log5((x^2)/(3x))=1

then x^2/3x=5^1

x^2/3x=5

And well, I forgot what you do next...

I think he means 1= log5(5)

Just out of interest, do you mean:

2^(2x+3) = 3^(3x+2)

or

(2^2x)+3 = (3^3x)+2

If it's the first one my photo was wrong. This one is right

Also there's always one log question which is quite hard

13. Are you guys just writing your logs weirdly or do you not have bases?

Thank you! I was struggling on this for quite a while, now it makes sense

I am lazy
You are allowed to miss bases out for base 10 I think

Posted from TSR Mobile
When you write something like log6,
the base is automatically assumed to be 10.
