Question

Sa raspunda cineva va rog ^_*


1. 5^27:25^13+5^2^0x[625:5^4:(5x5^2-120^1)]
2. 2^30:3^25+2^40-2x[128:2^5+2^3:(2x2^4-24)]
3. Ultima cifra a lui: N=1^33+4^34+7^35

Answer 1

1.  5^27÷5^26 +5 ×[5^4÷5^4÷(125-120)] = 5+5×1/5 = 5+1 =6

2.  2^5+ 2^40 - 2×[2^7÷2^5 + 2³÷(32-24) ] = 2^5+2^40 -2· [4+1]=2^5+2^40 - 10 = 22+2^40 = 2(11+2^39)........ ai scris ceva gresit!!!!!

3.  Uc(N) =Uc(1^33) +Uc(4^34) + Uc(7^35) = 1+6 +Uc[7^(32+3)] =7+3 =0

OBSERVATII:  Uc(4^impara) =4    Uc(4^para )=4
