For example, a student might write 8 x 8 x 8 x 8 x 8 and explain that 8 x 8 x 8 x 8 x 8 is equal to because eight is the base since it is the factor in the multiplication, and five is the exponent because there are five factors of eight.
To reinforce the meaning of the exponent, initially encourage the student to write exponential expressions in expanded form before calculating e. Instructional Implications Provide instruction on the meaning of exponents.
