in this video we're going to focus on

how to simplify radicals with variables

and exponents so let's say if you want

to simplify the square root of x to the

fifth the index number is a two now one

way you can do this is you can write x

five x and because there's a two you

need to take out two at a time so this

will come out as one X and this will

come out as another X and you're going

to get x times X square root of one at

just X by itself so this is equal to x

squared root X now another way you can

simplify this or get to the same answer

is if you do it this way how many times

is to go into five two goes into five

two times because two times two is four

two times to be at six that's too much

and what's remaining 5 minus 4 is 1 so

you get one remaining that's another way

you can simplify it so let's say for
