Logarithms with exponents and variables

WitrynaLogarithms are undefined for base 1 because there exist no real power that we could raise one to that would give us a number other than 1. In other words: 1ˣ = 1 For all real 𝑥. We can never have 1ˣ = 2 or 1ˣ = 938 or 1ˣ = any number besides 1. If … WitrynaTo solve for x x, we must first isolate the exponential part. To do this, divide both sides by 5 5 as shown below. We do not multiply the 5 5 and the 2 2 as this goes against …

WitrynaIn my math textbook the answer to a logarithm is given as log_a (sqrt of a/x) I reasoned that this would equal log_a (sqrt of a) - log_a (x) The square root of a is equal to a to the 1/2 power. So log_a (a^1/2)=1/2 Therefore, it simplifies to 1/2- log_a (x) Is this wrong or would the book answer be considered simpler? • ( 3 votes) Just Keith When the base is Euler's Number e = 2.718281828459...we get: And the same idea that one can "undo" the other is still true: ln(ex) = x e(ln x)= x And here are their graphs: They are the same curve with x-axis and y-axis flipped. Which is another thing showing us they are inverse functions. Always try to use … Zobacz więcej A Logarithmgoes the other way. It asks the question "what exponent produced this?": And answers it like this: In that example: 1. The Exponent takes 2 and 3 and gives 8 (2, used 3 times in a multiplication, makes 8) 2. The … Zobacz więcej Exponents and Logarithms work well together because they "undo" each other (so long as the base "a" is the same): They are "Inverse Functions" Doing one, then the other, … Zobacz więcej What if we want to change the base of a logarithm?
