Explanation:

Left to right, the expressions simplify to π, -1, π^2, √2.

1. Perform the division and you get 5π-4π = π.

2. Perform the division and you get √4 -√9 = 2-3 = -1.

3. Perform the multiplication and you get π^2. (The radicals become √1.)

4. If you just multiply it out, you get (10/3)√(18/100) = (10/3)(3/10)√2 = √2.
