Logaritmi – kako za vraga gre to? Majcha?

a) loga a2)-3 + (loga (1))3 = a-3 + 03 = a-3 ???

b) loga x2 + loga 1/x2 = loga x2 – loga x2 = 0 ???

c) ½ log (4) + 3 log (6) – 2 log (3*22) = (hmmmm: –log (4) + 6 log (6) – 4 log (3))) ???

d) logt √a + logt √(ab)-1 + ½ logt (b) = ½ logt (a) + ½ logt (a-1) + ½ logt (b-1) + ½ logt(b) ??? In potem?

😳 …. Ah ja: moj novi … elektronski park?
