Calculator?
Yes, your answer is close, but not to the ten-thousandth.
Are you supposed to do this by hand? It's easy with a calculator.
Try the Babylonian method. It works great for doing square roots by hand.
This is a recursion, where k= an estimate and b is what your finding the squre root of.
Here's an example:
Suppose you want to find
We know it's going to be between 3 and 4. Because 3^3=9 and 4^2=16.
Make an intitial guess of, say, 3.3.
Keep that up until you get the desired accuracy. But, I believe we're there already.
Now do it with.
