Why does a logarithmic equation sometimes have an extraneous solution?

Mathematics
2 answers:
jonny [76]2 years ago
6 0

The main reason behind this is using properties of logarithm .

like

when solving

  • log_2(x+2)+log_2(x-3)=3

There you use multiplication property and make addition to multiplication then you get extraneous solution because in plenty of cases they occur

like

  • (-2)²=(2)²

But

  • -2≠2

Same happens in case of logarithm
