APP description

Enter numbers using a comma (,) or a space or a tab or a separate line.

Also known as "ten decimal". The base 10 logarithm is indicated by the symbol "lg". For example, lgA represents the logarithm of A with base 10, where A is a true number. The common logarithm of any positive number can be expressed as the sum of an integer and a positive pure fraction (or zero); the integer part is called the "first number" of the logarithm, and the positive pure fraction (or zero) is called the pair. The "mantissa" of the number. The commonly used logarithm has a logarithmic table to check.

Express a positive number in scientific notation as a product of a fraction containing a single integer and a power of an integer of 10 and then take the common logarithm

Example：\(lg200=lg(10^2*2)=lg10^2+lg2=2+0.3010\)

\(lg20=lg(10^1*2)=lg10^1+lg2=1+0.3010\)
