To solve the equation 2^(3z + 9) = 8^(2z + 1), we can start by simplifying the bases of the exponents.
Let's rewrite 8 as 2^3 since they have the same base:
2^(3z + 9) = (2^3)^(2z + 1)
Using the property of exponents (a^(m*n) = (a^m)^n):
2^(3z + 9) = 2^(3*(2z + 1))
Now, since the bases are the same, we can drop them, so we have:
3z + 9 = 3 * (2z + 1)
Next, distribute the 3 on the right side of the equation:
3z + 9 = 6z + 3
Moving all the terms with 'z' to one side of the equation and the constant terms to the other side:
3z - 6z = 3 - 9
Simplifying:
-3z = -6
Now, divide both sides of the equation by -3 to solve for 'z':
z = -6 / -3
Finally, simplify:
z = 2
Therefore, the solution to the equation 2^(3z + 9) = 8^(2z + 1) is z = 2.
