Find the value, or values, of π₯ if
12π₯ to the fifth power equals 384.

Weβre going to solve this equation
for π₯ by performing a series of inverse operations. We notice that π₯ to the fifth
power is being multiplied by 12. So weβre going to begin by dividing
both sides of this equation by 12. 384 divided by 12 is 32. So we get π₯ to the fifth power
equals 32. Then, to solve this equation, we
recall what we know about even and odd roots. Specifically, given the equation π¦
to the πth power equals π₯, if π is odd, then there is exactly one solution to
this equation, π¦ equals the πth root of π₯.

Now, since our equation is in terms
of π₯, weβre going to rewrite this slightly. So if π₯ to the πth power equals
π¦, then π₯ is equal to the πth root of π¦. Now, in this case, π is odd; itβs
equal to five. And so there is just one solution
to this equation. Itβs π₯ equals the fifth root of
32. But of course, the fifth root of 32
is simply equal to two. And so, the solution is π₯ equals
two.
