División en forma exponencial
Cuando se divide dos términos en forma exponencial y con la mismabase se restan los exponentes (al exponente numerador se le resta al denominador).
Ejemplo:
A6/ a2 = a6-2 = a4 104/105= 10-1
--------- ------------ ------------------------- -------------- --------
B3/b2= b1 c2/c3 = c-1 d3/d4= d-1 103/102=101 104/105=10-1 106/103=103

5x104/2x102=2.5x102
3x103/4x102= 0.75x10110x105/2x104= 5x101 4x106/2x104= 2x102
(3x108)(6x10-5) / (2x103)(3x10-7) =3x107 =300x106
(4x106)(3x10-2) / (2x104)(3x10-9) = 2x101 = 2x109
(1x102)(3x103) / (2x104)(4x10-7) = 0.375x102 =37.5x1006
(3.6x100)(6x108)(8x107) / (6x102)(1.2x10-5) = 24x1018
(3.8x107)(4.8x106)(9.6x10-4) / (1.9x10-6)(6x102)(1.2x10-5) = 12.8x1018
(4.4x107) / (1.9x10-6) = 2.3157x1013
(4.4x10-5)(8.4x10-1) /(6x102)(1.2x10-5) = 5.13x10-3
(7x10-7)(3.42x104) / (5x10-3)(5x10-2) = .9576x102
(4.8x103)(3.42x10-4) / (4.76x106)(8.4x10-1) = .410x10-6
