Location: Southside | My students where wondering why we need to learn how to simplify radicals, particulary those with binomal radicals like 1+ sqrt(2) and such.
I could explain to them why it is important for general radicals, pythagoren theorem and such but aside from advanded math theory I can not think of a basic real life problem that would envolve divison by a radical in binomial form...... Any ideas? |

Location: Bryan Station | I don't have a good answer to your question. My students have asked the same thing to which I reply it helps them in their future math classes and their ability to think mathematically.
I do however want to share a great program for a general class to use towards the end of this unit. It's called Zoom Alg and is free download from TI. For those of you that haven't used it or heard about it, it will simplify radicals, simplify algebraic expressions, and simplify fractions. It's a great program! |

| If you have a variable under the radical, that relates to Pythagorean Theorem, because you could be missing the leg, but know the other leg and hypontenuse. |

Location: Southside | Ohhh good thought, but how could you arive at a problem such as....
1
1 + sqrt(2)
