9^2x = 27^(3x-2)
To solve for
x, we will use the exponent properties to find x.
First we
will rewrite the bases as powers of prime numbers.
We know
that:
9 = 3^2
27 =
3^3
Let us
substitute.
==> 3^2)^2x =
(3^3)^(3x-2)
Now we know that x^a^b =
x^ab
==> 3^(2*2x) =
3^(3*(3x-2)
==> 3^(4x) =
3^(9x-6)
Now that the bases are equal, then the powers are
equal too.
==> 4x = 9x
-6
==> -5x =
-6
==> x =
6/5
