How to use log to solve for exponent

WebImagine we have two numbers a and b. We want to find the result of multiplying the two numbers, i.e. to find ab. Take the log of ab and using the addition rule of logarithms: log ab = log a + log b. Take the antilog of both sides. antilog (log ab) = antilog (log a + log b) … WebUse the Exponential Function on both sides: 3log3(x) = 35 And we know that 3log3(x) = x, so: x = 35 Answer: x = 243 And also: Example: Calculate y in y = log4(1 4) Start with: y = log4 (1 4) Use the Exponential Function on both sides: 4y = 4log4(1 4) Simplify: 4y = 1 4 …

Web16 nov. 2024 · We need a way to get the x x out of the exponent and luckily for us we have a way to do that. Recall the following logarithm property from the last section. logbar = rlogba log b a r = r log b a Note that to avoid confusion with x x ’s we replaced the x x in this property with an a a. WebTo represent y as a function of x, we use a logarithmic function of the form y = logb(x). The base b logarithm of a number is the exponent by which we must raise b to get that number. We read a logarithmic expression as, “The logarithm with base b of x is equal to y, ” or, simplified, “log base b of x is y.
