Just take 3^4, which now becomes 3^2 = 9, outside the square root to leave (1+ 3^3)/7 inside the square root. The latter is easily calculated as 4 inside the square root. So 9*2 = 18.

Are you a teacher? I had a math teacher that would use the same style on a black board. Every problem he would go back to the basics for each step.
