Question 1006907: Log rules question
ln((a^2)/(b^2)(c^1/2)) if I were to use log rules on this what would happen to the denominator? would it be added because it's a product in the denominator?
I would think it would be:
2ln(a) - 2ln(b) +(1/2)c
But online ive seen it as:
2ln(a) - 2ln(b) - (1/2)c
Why is it minus for the denominator I thought it was any products become addition?
