Solving Exponents and Powers
We know how to solve the problem 5 x 5. This expression can be written in a shorter way, using something called exponents.
5 x 5 = 5^2
An expression that represents a repeated multiplication of the same number is called a power.
The number 5 is called the base, and the number 2 is called the exponent. The exponent corresponds to the number of times the base is used as a factor.
Evaluate the problem: 3^2 x 4 = ?
1) Using PEMDAS (parenthesis, exponent, multiply, divide, add, subtract), first solve the exponents: 3×3 = 9
2) Rewrite: 9 x 4 = ?
3) Solve: 36
