na jutro !! ;d

Answer 1

6 * 2^8 - 2^3 * 2^5               6*2^8 -2^8                  5*2^8
         -- -- -------------- = -------------------------   =------------------   =1/2 *2^2=1/2 *4=2
       10 * 2^6                           10*2^6                      10*2^6
b7 * 3^15 : 3^4 - 5 * 3^5 * 3^6        7*3^11 -5*3^11         2*3^11
---------------------------------------=------------------------=------------=1/2 *3^2=9/2=4 1/2
                    4 * (3^3)^3               4*3^9                       4*3^9

c c) 9 * 3^4 - 2 * 3 ^5  9*3^4 -6*3^4            3*3^4
     ----------------------=-----------------------=------------=3
        (3^2)^2                  3^4                       3^4

d)11 * (5^4)^5 - (5^3)^7      11*5^20 -5^21         11*5^20-5*5^20    6*5^20
  -----------------------------=-----------------------=----------------------=----------=1
     6* 5^23 : 5^3          6*5^20                             6*5^20              6*5^20

e)7 * 3^12 + 5 * 3^11       21*3^11 +5*3^11      26*3^11
   ---------------------------=-----------------------=--------------=3^1=3
         26 * (3^2)^5            26*3^10                   26*3^10

f)2^6 * 2^3 + 6 * 2^5        2^9 +6*2^5      16*2^5+6*2^5  22*2^5
   --------------------------=-----------------=----------------=-----------------=22 *2^-5
       2^10                           2^10                2^10              2^10
