Q1  Evaluate the iterated integral by converting to polar coordinates
∫0 to 2 ∫Sqrt 4x^2 to Sqrt 4x^2 e^(x^2y^2) dy dx
The region of integration is bounded by
Sqrt 4x^2 ≤ y ≤ Sqrt 4x^2 and 0 ≤ x ≤ 2
Q2  Evaluate the triple integral ∫∫R∫ OR ∫∫∫R f(x,y,z)dV
With f(x,y,z)=Sqrt y 3z^2
Q = {(x,y,z)/2 ≤ x ≤ 3, 0≤ y ≤1, 1≤ z ≤1 }

Q1) By moving to polar coordinates you end up with $\displaystyle \iint_D e^{r^2}\cdot r\cdot drd\varphi$ where $\displaystyle D=\left\{0\leq r \leq 2,\ \frac{\pi}{2}\leq \varphi \leq \frac{\pi}{2}\right\}$
The second question looks a bit strange (the limits for x).
