number必須
The positive real number for which you want the base-10 logarithm.
The LOG10 function calculates the exponent to which 10 must be raised to equal the specified number. It is commonly used in scientific calculations, such as measuring sound intensity in decibels or pH levels.
=LOG10(100)→2Since 10 raised to the power of 2 equals 100, the result is 2.
=LOG10(1000)→3Since 10 raised to the power of 3 equals 1000, the result is 3.
