Solve the equation by expressing each side as a power of the same base and then equating exponents.
3(^3x+6)=1/27
Please show every step and explain how you got it.
Thanks!

1/27 = 3^(-3)

3^(3x+6) = 3^(-3)

When bases are the same, all you need to do is set the exponents equal to each other:

3x+6 = -3
3x = -9
x = -3
Hope it helped you.
