Expert Solution
Step 1

We have to evaluate the integral I = 02x13ex2 dxdy
We can see that the limits of y are dependent on x, and limits of x are constant functions. So, first we will change the order of integration from dx dy to dy dx. 
The region under consideration is shown below.

Step 2

By changing the order of integration, we get the new integral as

I = 1302xex2dy dx  = 13ex2 [y]02x  dx  = 13ex2[2x-0] dx  = 132x.ex2 dx 

Now, we shall proceed with the integration by  substitution method.

Let x2=t 2x dx = dt.
The new limits are : x=1t = 1; x = 3 t = 9
