Let P = number of problems solved per day.
P = 448/28
P = 16
Lisa solved 16 problems per day.
2.5 hours i think but i might be wrong :)
The answer is: False.
If a logarithm is written without a base <span>it IS NOT a natural logarithm.</span>
The explanation is shown below:
1. I<span>f a logarithm is written without a base, you must assume the base is 10. It is written as below:
log(x)
</span>
2. It is important to know that the base <span>a natural logarithm is the irrational number e. It is written as below:
ln(x)</span>
