Divide and simplify. Assume that all variables are positive.

Step-by-step explanation:

For this we have to divide like normally but for the exponents we will subtract them since this is a division problem. We would've added them if we were multiplying.

Now we will split the 8 into 4 and 2. Also we can take the square root of y² while we're at it.

Now we take the square root of 4.
