For part I) simply key into your calculator the entire expression. Can sub t= 10000 into the expression.
For part 2) remember your ln rules. It’s the same as logarithm rules but ln is base e and not base 10. We use ln here because of e. Slowly manipulate the expression till you can express t.
Hope it helps!
