Logarithmic and Trigonometric Tables

in this lesson we're gonna focus on solving basic logarithmic equations let's start with this one log base 2 of 16 is equal to X go ahead and find the value of X what we need to do is convert it to exponential form two raised to the X is equal to 16 now you might already see the answer but I'm gonna go ahead and solve it now we know that 2 to the fourth power is 16 so therefore X is equal to 4 you can also do this log of 16 divided by log of 2 if you type that in that's equal to 4 which is X using the change of base form try this one log of X log base X of 81 is equal to 4 what is X so let's convert it to its exponential form X to the fourth is 81 so now let's find the value of x to do that we need to take the fourth root of both sides so the fourth root of 81 is equal to 3 because 3 to the fourth is 81 now what about this one log base 5 of X is equal to 3 convert it to its exponential
