Corrections!

Today our class had two math classes. In the first class we passed our homework to the person beside us and corrected it. For Homework we had to do page 85 #5 to 12. Some of the students didn't know or forgot how to discover the square root. Mr.Oldcorn then showed the class three different ways to find a square root of a number, which would then find the perfect square.
Here is what he suggested for the class.

  1. guess and check,



2.Use a calculator,


3.Prime factorization,


Thats most what we did, But I'll post more tomorrow!
Don't forget your homework for tomorrow,
Page86 #13,15,17,19 and 21!
