Log<sub>2</sub> 10 is a function with the base 2 of 10 as the true number.
Log<sub>2</sub> is a function that takes 2 as a true number.
Logarithm is an exponential operation. For example, log<sub>2</sub>x means how many times x is 2.The monotonicity of the logarithmic function is divided into two categories according to the magnitude of the base a and 1.a>1, increasing, a<1, decreasing.log<sub>2</sub>x<1=log<sub>2</sub> 2 (2 is the base, logarithm of 2) so x<2,real number x>0, so 0<x<2 Then let me talk about the calculation of lg.lg is the logarithm to base 10.For example, lgx=y, which is equivalent to the 10<sup>y</sup>=x,the following lists some calculation formulas for lg,lgA+lgB=lg(A * B ) lgA-lgB=lg(A/B),there is also ln, which represents the natural logarithm, which takes e as the base.
