– Explanation of the exponent formula

ax鈫�a is the base and x is exponent.

The power is the result of repeated multiplication of the same factor.

The expressionsaxthis means that a has been used as a factor x times

02

Find the base and exponent of 34 and evaluate

Example: Find the base and the exponent of 34 and write in repeated multiplication.

Rule: ax鈫�a is called base and x is power.

a = 3 and x = 4

Base = 3 and power = 4

In repeated multiplication: 34鈥�鈥�=3鈥�路鈥�3鈥�路鈥�3鈥�路鈥�3鈥�
