How do you do logarithms in math?
logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8.
What is the easiest way to learn logarithms?
Know and apply the properties of logarithms.
- loga(xy) = logax + logay.
- loga(x/y) = logax – logay.
- loga(xr) = r*logax.
- loga(1/x) = -logax.
- logaa = 1.
- loga1 = 0.
- (logbx/logba) = logax.

Why are logarithms so hard?
The change of base part produced an extra step that was difficult to identify and deal with. Because the rules for logarithms are so suprising in a way, it is a bit like solving a puzzle where the steps in the puzzle are so entangled with themselves, that it becomes complicated to keep track of your moves…
In what grade do you learn logarithms?
Indeed, students don’t usually learn anything about logarithms until Algebra 2 or even Precalculus.
Are algorithms and logarithms the same?
Algorithm is a noun meaning some special process of solving a certain type of problem. Whereas logarithm, again a noun, is the exponent of that power of a fixed number, called the base, which equals a given number, called the antilogarithm.
