in your head, work out the APPROXIMATE square root of 165 up to two decimal places OR give the remaining decimal fraction.

eg. for 137 i would accept 11.73 or 11+8/11 or even 129/11 if you will.

go on, give it a shot!

Scruffy23: I have a challenge for you !!. Work out the square root of 165 using "Newton's Method" to at least 5 decimal places. You can use a calculator but NOT the "sqrt key".
