36^(2x+4) = (square root of 1296)^x
Solve for x
I'm really stuck on this one too, thank you for your help
LOL !!! sqrt 1296 = 36
2x+4 = x
1)x = 6
2)x = -6
3)x= 0.0000 - 6.0000 i
4)x= 0.0000 + 6.0000 i
I don't understand
36^(2x+4) = (square root of 1296)^x
36^(2x+4) = 36)^x
2x+4=x
x=-4
check: 36^(-8+4)=36^-4
checks ok. Am I missing something here?
