Hi; I need to expand log4(x^2 + 9)/log4(x^2  6x + 8)^2/3. the 4 is tha base. 2/3log4(x^2 + 9) / 2/3log4(x^2 6x + 8) 2/3log4x^2 + 9  2/3log4x^2  6x +8 This is where I not sure with the quadratic I guess you just expand it giving 2/2log4x^2  2/3log4(x  2) + 2/3log4(x + 4) and thats it I think.

Surely the division becomes subtraction and you missed the 2/3 off.
