Hello students.

Today we will discuss about this question.
00:03
In this question, we need to evaluate the following the double integral over r region, that is, double integral over our square root of x divided by y, da, when r is equal to x, comma, such that 0 less than or equals to x, less than or equals to 1, and 4 less than or equals to y less than or equals to 16.

Now here we need to choose two integral that are equivalent to double integration over our square root of x divide by y d a.
00:48
So here we can write we are given four option option a that is integration 0 to 1 integration 4 to 16 square root of x divide by y, d .y, dx.
01:03
Option b, that is, integration 4 to 16, integration 0 to 1, square root of x divide by y, dx, d, y.
01:16
Option c, that is, integration 0 to 1, integration 4 to 16, square root of x divided by y, dx, and option d, that is, integration 4 to 16, integration 0 to 1, square root of x, x, divide by y, dx, and option d, and option d, that is integration, x divide by y, d y, d x.

So here we need to write the correct equivalent...
