Square Roots

Postby PatriotAlanis » Thu Mar 18, 2010 6:24 pm

How do you all do these?? Im referring to the truncation of the sums and differences in irrational squares. Memorization? Linearization? Newton's Method? Im curious.

Could you make your question more precise? Are you taking the square root of an irrational number?

questions like sqrt(2) + sqrt(3) or sqrt(5) + sqrt(7) truncated to two decimal places. sqrt(8) - sqrt(6) was the last one i saw i believe.

At the SAC, Mr. White mentioned that students should know the square roots of the first ten positive integers to two decimal places.
Irrelevant since 2007.
