Exponents are a shorthand way to
show a larger number.
What is an exponent?

How do you read an exponent?
A number with an exponent is said to be
"raised to the power" of that exponent.
Let’s look at some examples. . . .

32 = three raised to the second power or three
squared53 = five raised to the third
power or five cubed
74 = seven raised to the fourth power

An exponent tells how many times the base is multiplied
by itself.
What does an exponent mean?
73 means 7 x 7 x 7 or 343

Any number raised to the 0 power is equal to one!
100 = 1
Helpful Tips
Any number raised to the 1st power is equal to the number
itself.
81 = 8

The most common mistake is……
BE CAREFUL
43 = 4 x 4 x 4 = 64
Why is this not correct?43 = 4 x 3 =
12This is correct…..
