Write the following exponential formula as logarithmic formula or the following logarithmic formula as exponential formula 53 square = 125, 10x square = y INX = y log subscript 216 = 4 Think about that log

Write the following exponential formula as logarithmic formula or the following logarithmic formula as exponential formula 53 square = 125, 10x square = y INX = y log subscript 216 = 4 Think about that log

1. Log subscript 5 125 = 3
2. Log subscript 10 y = x or lgY = x
3、e^y=x
4、2^4=16
Log is logarithm
Ln is the natural logarithm, that is, taking the logarithm of E as the base (equivalent to log subscript e)
LG is the common logarithm, which is the logarithm based on 10 (equivalent to log subscript 10)

On how to write logarithmic formula into exponential formula
Questions such as:
（1）X=㏒5 27
（2）X=㏒7 1/3
（3）X=㏒4 3
（4）X=㏒8 7

5^X=27
7^X=1/3
4^X=3
8^X=7
There is no process. That's the definition of logarithm

Exponential is written as logarithmic
How to change the exponential formula into the logarithmic formula

The x power of a is equal to n
Log is based on a, and the logarithm of n is equal to X
