(11^2011 * 2^2010)/[(22^2)^5]^201 =
(11^2011*2^2010)/ (22^10)^201=
(11^2011*2^2010) / 22^10*201 =
(11^2011*2^2010) / 2^2010 =
Nu stiu daca este bine pana aici si daca da, cum rezolv mai departe ?

    Salut,

    La ultima linie, la numitor ar fi 22^2010, nu doar 2^2010:

    \bl\frac{11^{\small 2011}\cdot 2^{\small 2010}}{22^{\small 2010}}=\frac{11\cdot 11^{\small 2010}\cdot 2^{\small 2010}}{22^{\small 2010}}=\frac{11\cdot (11\cdot 2)^{\small 2010}}{22^{\small 2010}}=\frac{11\cdot22^{\small 2010}}{22^{\small 2010}}=11

    Linia de fractie inseamna o impartire ! (numarator : numitor) …
