Week 1- Pre-Calc- square roots

This week in math we learned about square roots. I chose to show my understanding of this because it is an important starting point for math 11 and I had forgotten how to do this in previous years.

There is sometimes an index number and a radical in a square root. In this example, \sqrt{25} the 25 is radical, and in order to find the square root we need to find the number that goes into to fully. In this case, it would be 5.  \sqrt{25} =5

Another example of estimating a square root, is in this example we can find what two integers is the value of this radical. \sqrt{75} = 8 and 9 because 8^2 = 64 and 9^2 = 81 so it would be between 8 and 9 or 8.5. \sqrt{75} = 8.5 estimated
