I've started accelerated geometry now, in 8th grade, and an algebra review packet is due. I really need help to remember how to do problems like -

[square root of] 48rs^3

[square root of]63 + [square root of]28 - [square root of]1/7

3[square root of]5x

------------------- (over)

5[square root of]6y

x^2 + 2x + 1

----(over)

3x

-------------(all over)

x+1

----(over)

2x

Sorry, I didn't know how to use the math tags. I hope you will be able to read it.

Could someone please solve these and then show me how they did it?
