Oblicz wartość wyrażenia (log5)^2+(log2)^2+log 4* log5     ^-do kwadratu

[ log 5  + log 2 ] ^2 = ( log 5)^2 + 2 *log 5 *log 2 + ( log 2 )^2 = =( log 5)^2 + log 5 * 2 log 2 + ( log 2 )^2 = ( log 5 )^2 + log 5 * log 4 + ( log 2 )^2 czyli ( log 5)^2 + ( log 2 )^2 + log 4 * log 5 = [ log 5 + log 2 ]^2 ==================================================
