Using the property of exponents below.......and taking.......2 to the 1 + 2i..................might be seen to create a rectangle..........

henever you multiply two terms with the same base, you can add the exponents:

( x m ) ( x n ) = x( m + n )

However, we can NOT simplify (x4)(y3), because the bases are different: (x4)(y3) = x‍x‍x‍xyyy = (x4)(y3). Nothing combines.
