Question

Va rog ajutatima dau coroana! Calculati puterile:
11^{6} : 11^{2} :11 · 11^{3} : 11^{4} =
(3^{4} )^{5 } ·5^{4} =
16^{4} ·4^{5} :2^{5} =
(5^{3} ) ^{4} · 5^{4} =
27^{5} · 9^{6} : 3^{3} =

Answer 1

1)11^6:11^2=11^4
11^4:11=11^3
11^3×11^3=11^6
11^6:11^4=11^2=121
2) (3^4)^5×5^4=
81^5×5^4=
81^5×625=
(81×625)^5
3) 4^5=16^4; 2^5=16^2
16^4×16^4 : 16^2= 16^6
4) (5^3)^4=5^12
5^12×5^4=5^16
5) 9^6=27^5; 3^3=27
37^5×27^5:27=27^9
