Answer:
x = -2/3
Step-by-step explanation:
27 ^(x+2) = 81
Rewrite 27 as a power of 3
27 = 3^3
Rewrite 81 as a power of 3
3^4
3^3^(x+2) = 3^4
We know that a^b^c = a^(b*c)
3^3*(x+2) = 3^4
3^(3x+6) = 3^4
The bases are the same so the exponents are the same
3x+6 = 4
Subtract
6 from each side
3x+6-6 =4-6
3x = -2
Divide by 3
3x/3 =-2/3
x = -2/3
