5. A power is an expression that represents repeated
multiplication of the same factor.
Example – 64 is a power of 4 because 4 x 4 x 4 equals
64
A power can be written using two numbers a base
and an exponent.
 n2 n to the second or n squared
 n3 n to the third or n cubed
 n4 n to the fourth
 n5 n to the fifth
