Does anyone know the steps to figure out problems that include natural logarithms? - how to figure out the problems in poptropica game
I'm really terrible in math and could help me, if I understand a set / list of steps that had most problems. Thank you!

ABC: natural logarithm to base 10 are logged.
Natural logarithms base e ≈ 2.71828 is written and ln.
Base 10 logs are sometimes referred to as common core written in the registration form. If not specified in the base of the logarithm to the base 10 supports.
The basis of what you need is all that is the base of the exponent in question. For example:
^ 7-5 (2x-1) = 4
Here is the base is 5 because 5 is raised to a power. The first step is to identify the role of:
5 ^ (2x-1) = 7 to 4 = 3
Thus 2x - 1 = log_5 (3)
So x = (log_5 (3) + 1) / 2
= (Log 3 / log 5 + 1) / 2
= 0.8413 to 4 dp
4e ^ (2x) = 5
Here is the base is e, so we will use the natural logarithm:
e ^ (2x) = 5 / 4
If 2x = ln (5 / 4)
So x = (1 / 2) ln (5 / 4) = 0.1116-4 dp
So the idea is to isolate the exponential, like any other variable, then take the ball on the ground. What in the exponent, which is an expression of the shared variables. Then you can isolate and fix the variable. Remember, the newspapers to a non-s to calculatetandard database, use the rule log_e (b) = log_c (b) / log_c (a), as above log_5 rewrite (3) above log 3 / log 5th Note that ln 3 / LN 5 works well, because the rule works for all c.
1. Use a calculator if you can. The graphing calculator can do most of the problems of natural logarithms.
2. If you use the recording problems, you know that all questions will be taken for registration on the basis of a series. Natural logs are base 10
Based = 10 log.
If you solve this problem, how many times to remember how to do a way to check the numbers with the problem in establishing connection.
In other words, if the problem as follows:
ln (5x) = 3y
Draw a line between the 5x the NL and LN 3y. To begin with the 5-fold, in turn, the base 10, and solve for y.
if u give examples of problems, then it would be useful for you. otherwise it is very difficult to understand these things.
