Powers with Positive Bases.
4² can be read as "four squared." You can use an imaged model of a square to represent the power.
How does the model of the square represent 4²?
Each side of the square is 4 units in length. The area of the square is 16 because there are 16 small squares altogether in the square.
In the power 4², the base is 4 and the exponent is 2.
4² = 4x4
=16
2 to the power of 3 can be read as "two cubed."
\you can use a model of a cube to represent the power.

2 to the power of 3 can be read as "two cubed."
\you can use a model of a cube to represent the power.
Each of the large cube is 2 units in length.
The volume of the large cube is 8 because there are 8 small cubes altogether in the large cube.
In the power 2 to the power of 3 the base is 2 and the exponent is 3.
2 to the power of 3 = 2x2x2
= 8
