a) (5^2)^7 / (5^3)^5 * 5^47 = 5^14 / 5^15 * 5^47 = 5^(14-15+47) = 5^46

б) (3^4)^16 : (3^2)^30 * 3^4 = 3^64 : 3^60 * 3^4 = 3^(64-60+4) = 3^8

в) (2^3)^12 : (2^4)^4 * (2^5)^10 = 2^36 : 2^16 * 2^50 = 2^(36-16+50) = 2^70

г) (6^3)^-13 * (6^2)^12 : 6^-16 = 6^-39 * 6^24 : 6^-16 = 6^(-39+24-(-16)) = 6^1

д) (2^6)^14 : (2^2)^40 * (2^4)^-2 = 2^84 : 2^80 * 2^-8 = 2^(84-80-8) = 2^-4

e) (7^2)^-16 : 7^15 * (7^3)^16 = 7^-32 : 7^15 * 7^48 = 7^(-32-15+48) = 7^1
