Be precise. multiplication is defined as repeated addition. use the word repeated to define exponential form. justify your reasoning.

Well,

2²  =  2 · 2
2³  =  2 · 2 · 2
2⁴  =  2 · 2 · 2 · 2
2⁵  =  2 · 2 · 2 · 2 · 2
2⁶  =  2 · 2 · 2 · 2 · 2 · 2
2⁷  =  2 · 2 · 2 · 2 · 2 · 2 · 2
2⁸  =  2 · 2 · 2 · 2 · 2 · 2 · 2 · 2
2⁹  =  2 · 2 · 2 · 2 · 2 · 2 · 2 · 2 · 2
and
2¹⁰ =  2 · 2 · 2 · 2 · 2 · 2 · 2 · 2 · 2 · 2

It's sure starting to look like exponentiation is repeated multiplication.
