Exponents Part 1: Introduction
Exponential Notation - Notes
2.1 What is an Exponent?
An exponent is a letter or number placed
above and to the right of an expression.
Exponential form consists of a base and an
exponent.
In a numerical expression, the base is the
number raised to a certain exponent.
The exponent indicates how many times
to multiply the base by itself.
For example, consider "2^3":
Here, 2 is the base and 3 is the
exponent.
It is read as "2 to the power of 3."
To solve, multiply the base (2) by itself
three times: 2 * 2 * 2 = 8.
Writing "2^3" in expanded form: 2 * 2 * 2
= 8.
, This is known as exponential notation.
2.2 Squares and Cubes
The square of a base with an exponent of
2 is called a square.
Example: n^2 is "n squared."
Resulting number (n^2) equals the area of
a square with sides of length n.
The cube of a base with an exponent of 3
is called a cube.
Example: n^3 is "n cubed."
Resulting number (n^3) equals the
volume of a cube with sides of length n.
2.3 Square Roots and Cube Roots
If exponent = 2, result = square number;
if exponent = 3, result = cube number.
