To simplify
, remember that any non-zero number raised to the power of 0 equals 1. Thus,
, so
.
For
, first, rewrite it using the property of exponents:
. Therefore,
. Since
, it becomes
, so the result is
.
Next, to factorise
, first notice that both terms share common factors. The greatest common factor (GCF) is 3
, so factor that out:
. Voilà! You have the fully factored expression.
