I don't understand radicals. I mean, the basic ones are easy. But then you get into complicated craps with fraction powers and all this stuff. It just confuses me.
I know I'm gonna fail. Why waste my night studying for it then? I'm gonna do something I want to do. |

| Rationalizing denominators is pretty easy. |

For you, maybe. I'm stuck here wondering what to do.
Do I do the powers first? Do I add them together?
Do I separate each one and do them individually? Do I turn them into a fraction?
What? |

1 ------------- x^(9/2) y^(21/4)
is what i got. the ----- is just a line; the 1 is the numerator and the other stuff is the denominator

Yeah.
Too bad the tests are like the only parts of my grade even though I have to do these like math exercises every day. But I guess those don't do anything so why do I even do them.
Either way ill give you the name of the site that teaches me my math/gives me the exercises. Its called Khan Academy.
It'll probably help it make somewhat more sense. |

I'm so awful at math that I failed it last year.
I don't even know how to divide. |

| It's easy rationalizing denominators, if it's a odd number just multiply it by itself then find the square root |
