Matematicas Radicales - Tarea

Leyes de los Exponentes

• 0X = 0 Si X >0
• ax >0 si a > 0
• 00        =         ∞
• a0        =        1
• a-1          =        1/a                     si a ≠0
• a-x          =         1/ ax                    si a  ≠ 0
• (ab)x   =         ax  bx                si b ≠0
• (a/b)x  =         ax/bx                si  a,b ≠0
• [pic 1]   = [pic 2]= am/ n
• [pic 3]      = a1/n  n ≥ 2
• a-m/n =1/am/n  = 1/am/n = [pic 4]=[pic 5]

• 3 –2 * 52    = 1/9 *25 =25/9
• –22* ¼-1   =  -4 *4 * 1/([pic 6]) = -16 * 1/8 =-2
• 33 +70  -22  + (-2)3 + (-1/32)1/ 5= 27 +1 –4 + 1/-8 +(1/-32)5 =24 + 1/-8 +[pic 7]= 24 + (-1/8) +                   (-1/2)=    23.375
• [3x2/3- 2x1/3]3  =  (3x2/3) + 2(3x2/3)2 (-2x -1/3)3 = 27x2 + 2(9x4/3)(-2x1/3)+2(3x2/3)(4x2/3 )-8x =                                                                                         =27x2 –36x5/3+24x4/3 – 8x
• [pic 8]=[pic 9]=[pic 10]=[pic 11]=[pic 12]
