Your computer does have a square root format, but the keyboard doesn't. In order to compensate, the keyboard designer had made it that pressing ALT + 251 with the numbers in the function keys known as number locks.
This produces √
Now to solve your problem:

Since the square root of 16 is divisible by 4, you do not have to multiply the conjugate.

This is the final solution possible without using a calculator. Otherwise...
... and so on.
You're not on the right track however as square root and division are exactly the same.

You're on the right track!!
You now need to compute the square root of , which is: .
However, you didn't have to compute first. You could've easily used a calculator to calculate ,
which would give you the same result.
