The applicable rules of logarithms are ...
- ln(ab) = ln(a) +ln(b)
- ln(a/b) = ln(a) -ln(b)
- ln(a^b) = b·ln(a)
- ln(a) = b ⇔ a = e^b
Of course, a square root is the same as a 1/2 power.
If the can is 20oz and cost $25.40, the price per ounce would be:
price = $25.40
ounce = 20oz
so:
which comes out to be:
$1.27/oz
So each ounce of tomato sauce costs $1.27!
price = $25.40
ounce = 20oz
so:
which comes out to be:
$1.27/oz
So each ounce of tomato sauce costs $1.27!
