Răspuns:
a.) u ( 11^304 ) = u ( 1^304 )=1
b.) u ( 6^72 - 4^13 )=
u ( 6^72 )=6
u ( 4^13 )= u ( 4^3*4+1 )= u ( 4^1 )=4
u ( 6^72 - 4^13 )= 6 - 4=2
c.) u ( 4^136 + 9^81 )=
u ( 4^136 )= u ( 4^4*34 )=6
u ( 9^81 )= u ( 2*40+1 )=9
u ( 4^136+9^81 )= 6+9=15
d.) u ( 7^179+8^234 )=
u ( 7^179 )= u ( 7^4*44+3 )= u ( 7^3 )=3
u ( 8^234 )= u ( 8^58+2 )= u ( 8^2 )=4
u ( 7^179+8^234 )= 3+4=7
e.) u ( 2^1516+8^301+7^202 )
u ( 2^1516 )= u ( 2^4*379 )=6
u ( 8^301 )= u ( 8^4*75+1 )=8
u ( 7^202 )= u ( 7^4*50+2 )=9
u ( 2^1516+8^301+7^202 )= 6 + 8 + 9= 23
