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?

A 60 would be a miracle.

I love math, but my teacher only gives us math vocab tests. I hate them.

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
