What is the value of log 4 base 4?
Logarithm base 4 of 4 is 1 .
What is the value of log 3 81?
log381 is the same thing as writing 3x=81 , where you have to solve for x . 3 is the base number. 3⋅3⋅3⋅3 is 81 , proving 34=81 . So, 4 is the answer.

How do you solve log properties?
You can use the similarity between the properties of exponents and logarithms to find the property for the logarithm of a quotient. With exponents, to multiply two numbers with the same base, you add the exponents. To divide two numbers with the same base, you subtract the exponents.
How to evaluate log base 4 of 16?
log4 (16) log 4 ( 16) Rewrite as an equation. log4(16) = x log 4 ( 16) = x. Rewrite log4 (16) = x log 4 ( 16) = x in exponential form using the definition of a logarithm. If x x and b b are positive real numbers and b b does not equal 1 1, then logb (x) = y log b ( x) = y is equivalent to by = x b y = x. 4x = 16 4 x = 16.
Which is better a log reduction of 3 or 6?
As a basic rule of thumb, for every additional Log reduction number you add a 9 to the percentage reduction – so a log reduction of 3, as illustrated above, is a 99.9% reduction compared with a log reduction of 6 which is equivalent to a 99.9999% reduction.
How long does it take to read a log reduction?
Reading time: less than 2 minutes. In terms of infection control, ‘Log Reductions’ convey how effective a product is at reducing pathogens. The greater the log reduction the more effective the product is at killing bacteria and other pathogens that can cause infections.
What are the rules for expanding a log?
1) Multiplication inside the log can be turned into addition outside the log, and vice versa. 2) Division inside the log can be turned into subtraction outside the log, and vice versa. 3) An exponent on everything inside a log can be moved out front as a multiplier, and vice versa. Warning: Just as when you’re dealing with exponents,…
