The expression 25 is just a shorthand way of writing ‘multiply 2 by itself 5 times’. The number 2 is called the base, and 5 the exponent. Similarly, if b is any real number then b3 stands for b b b. Here b is the base, and 3. × ×. the exponent. If n is a whole number, bn stands for b b b . × × · · · ×. n factors.

- Exponentials and logarithms: applications and calculus
In this booklet we will demonstrate how logarithmic functions can be used to linearise certain functions, discuss the calculus of the exponential and logarithmic functions and give some useful applications of them.
Exponentials and Logarithms. 1 Exponentials. We have already met exponential functions in the notes on Functions and Graphs.. EF. A function of the form f ( x ) = ax , where a > 0 is a constant, is known as an exponential function to the base a. If. > 1 then the graph looks like this: y = , a > 1. ( 1,a ) 1 This is sometimes called a growth.
This topic introduces logarithms and exponential equations. Logarithms are used to solve exponential equations, and so are used along with exponential functions when modelling
Exponentials and Logarithms. This chapter is devoted to exponentials like 2x and 10x and above all ex: The goal is to understand them, differentiate them, integrate them, solve equations with them, and invert them (to reach the logarithm).
Exponentials and Logarithms. This chapter is devoted to exponentials like 2" and 10" and above all ex. The goal is to understand them, differentiate them, integrate them, solve equations with them, and invert them (to reach the logarithm). The overwhelming importance of ex makes this a crucial chapter in pure and applied mathematics.
1 EXPONENTS AND LOGARITHMS. WHAT YOU NEED TO KNOW. The rules of exponents: am × an = am+n. am • = am n an. (am)n = amn. m. a n am. a − n = an. an × bn = (ab)n. n an • =⎛ bn ⎝⎜. ⎞. ⎠⎟. The relationship between exponents and logarithms: a = b ⇔ x ga b where a is called the base of the logarithm. loga a x x. a log. x. The rules of logarithms: log. c.
