Oblicz:
c) 1080 * 6^4 + 6^7
--------------------
(6^3)^2
Ale nie obliczając potęg, tylko tymi zasadami działań na twierdzeniach.

[ 1080 *6^4 + 6^7 ] / ( 6^3)^2 = [1060* 6^4 + 6^7 ]/6^6 =
[ 1080 *6^4]/ 6^6 + 6^7 / 6^6 = 1080 * 6^(4-6) + 6^(7 - 6) =
= 1080* 6^(-2) + 6^1 = 1080 *(1/6^2) + 6 = 1080 : 36 + 6 =
= 30 + 6 = 36
