Logarithm is an important topic that needs to be prepared well for the Quantitative Aptitude section of exams. It requires practicing a lot of questions within a time limit. The logarithmic function is the inverse of the exponential function. It is defined as: y = log a x, if and only if x = a y; for x > 0, a > 0, and a ≠ 1.

The concepts of logarithm and exponential are used throughout mathematics. Questions on Logarithm and exponential with solutions, at the bottom of the page, are presented with detailed explanations.. Solve the equation (1/2) 2x + 1 = 1 Solve x y m = y x 3 for m.; Given: log 8 (5) = b. Express log 4 (10) in terms of b.; Simplify without calculator: log 6 (216) + [ log(42) - log(6) ] / log(49)
log a 1 = 0 and log a a = 1. From log a 1 = 0 we have that a 0 = 1, which is true for any real number a. From log a a = 1 we have that a 1 = a, which is true for any real number a. If in the logarithm the base is 10, then instead of log 10 we write lg. When we are solving some logarithm, any part can be unknown.
We have log 2 42 = 42 log 2 = 42 × (0.301) = 12.642 Now here the integral part is called the characteristic of logarithm and the fractional part is called the mantissa. The number of digits is always one more than the value of characteristic. The number of digits in 2 42 = 12 + 1 = 13 Hence answer is option C
Logarithm Functions – In this section we will introduce logarithm functions. We give the basic properties and graphs of logarithm functions. In addition, we discuss how to evaluate some basic logarithms including the use of the change of base formula. We will also discuss the common logarithm, \(\log(x)\), and the natural logarithm, \(\ln(x)\).
Precalculus: Logarithmic Functions Practice Problems Solutions 1. Find the inverse function f 1(x) if f(x) = e 3x +2. Verify you have the correct answer by checking that f(f 1(x)) = x. f(x) = e 3x + 2 y = e 3x + 2 x = e 3y + 2 interchange x and y x 2 = e 3y solve for y ln(x 2) = lne 3y solve for y ln(x 2) = 3y simplify using logarithm rules
