7) To solve the equation
, we can rewrite 27 as
and then use the property of exponents that states
implies
.
So, the solution to the equation
is
.8) To solve the equation
, we can rewrite 1 as
and 8 as
, and then use the property of exponents that states
implies
.
Since
is always equal to 1, we have
, which implies
, so
.So, the solution to the equation
is
.
