Integers solution =-1

Step-by-step explanation:

1 = 8^(3 x + 3)

1 = 8^(3 x + 3) is equivalent to 8^(3 x + 3) = 1:

8^(3 x + 3) = 1

8^(3 x + 3) = 2^(9 x + 9):

2^(9 x + 9) = 1

Express both sides with bases 2:

2^(9 x + 9) = 2^0

Equate exponents of 2 on both sides:

9 x + 9 = 0

All equations give x = -1 as the solution:

x = -1
