Question

folosind formula 1+a+a+a la puterea a 2 +...+a la puterea n = a la puterea n +1 -1 supra a -1 una a (este un egal taiat_1 si n apartine N.CALCULATI...... radical2x+1, unde x=1+3+3 la puterea a 2+3 la puterea a 3 +..+3 la puterea 249 VA ROG REPEDE DAU FUNDA SI COROANA

Answer 1

x=1+3+3^2+3^3+...+3^249=(3^250 -1)/(3-1)=(3^250 -1)/2

2x+1=2*(3^250 -1)/2 +1=3^250 -1+1=3^250

V(2x+1)=V(3^250)=3^125

''^''=la puterea
''*''=inmultit
''V''=radical
