The week we have been working on chapter twelve which is vectors and also had matrices like in chapter four but now the matrices are four by four. We also working on the aleks and it gave me an assestment quiz which i bombed and it took like twelve modules from me but its said i went up a couple point i do not know how i went up and fail the assestment. Lately on aleks i have been working on simplify radical expressions which is very so i want to do an example problem of that.
example problem
simplify the following problem
square root of 18x^5y^4z
okay simplify basically means breaking it down to its lowing forms
1. for 18 you can take the square root of nine and that lefts two up the square root
2. x^5 you can take 4 of the Xs because there is five so you put x^2 outside of the square and leave the other x in the square root
3.the same way for y^4 there are four ways so you can take them out and its not an out number so you can take all of it out
4. for the z there is only one of them that why there is no exponent next to it and since there isnt two or more you have leave
it in the square root
the answer is 3x^2y^2 with square root of 2xz
