Hence, the value of log 10 base 10 =1, this is because of the value of e1=1.
What is the log for 1?
As we know, any number raised to the power 0 is equal to 1. Thus, 10 raised to the power 0 makes the above expression true. This will be a condition for all the base value of log, where the base raised to the power 0 will give the answer as 1.
Is log 10 the same as 1?
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.
Why log 10 is 1?
Logs can also be figured for numbers less than one. When a number is a fraction (less than one), then the log is always negative. Why does this work? Because 10-2 is the same as 1/102, which equals 1/100, which equals 0.01!
How log 2 is 1?
log: (in math) An abbreviation for logarithm. logarithm: The power (or exponent) to which one base number must be raised — multiplied by itself — to produce another number. For instance, in the base 10 system, 10 must be multiplied by 10 to produce 100. So the logarithm of 100, in a base 10 system, is 2.
How do you calculate log?
Hence, we can conclude that logbx = n or bn=x where b is the base of the logarithmic function. This can be read as the “Logarithm of x to the base b is equal to n”. Thus, log 1 is written as log101 = 0.
Can a log be less than 1?
Loge ∞ = ∞, or ln (∞) = ∞ We can conclude that both the natural logarithm as well as the common logarithm value for infinity converse is at the same value, i.e., infinity. In similar ways, different values of logarithmic functions can be calculated and used to solve related problems.
What is log in math?
While the value of a logarithm itself can be positive or negative, the base of the log function and the argument of the log function are a different story. The argument of a log function can only take positive arguments. In other words, the only numbers you can plug into a log function are positive numbers.
How do you write log of 1?
