How do you find the exact value of this? √(7 - √(15 + √(7 - √(15

Also how do you find x and y? .. √x + √y = √8+√(15 + √60

Please leave an explanation! I really need to understand this for my exam! :)

ANy help is greatly appreciated!!

I was just wondering if anyone had any ideas for a 16th birthday party? We live across the road from a council swimming pool, but we don't have our own. I would like something low key but wanted my brother to be involved to. Are there any fun themes or ideas that might be suited to both of us (boy and girl)? (obviously no alcohol etc. is allowed). We aren't allowed to hire a venue or anything but I was thinking like maybe in the evening involving a photo booth, music, lolly bar, food, truth or dare etc. Should I theme it? Are there any other games that won't be too boring?

Thankyou! X

I have wanted to do some form of modeling for ages but my parents say I have to be 18+ because they don't agree with it.... If I continue to get the sort of grades I am receiving currently I will (hopefully) be getting an op2/ op1 !!!! This is the score I will be aiming for in yr 12 so I can get into a medicine course as I want to become a pediatrician.... I know that medicine school takes a lot of time and effort so I was wondering if I would be able to trial modeling on the side while studying medicine???

I'm 14 and I want to go to the One Direction concert. It takes about 30 minutes to get from my house to the concert. I could catch a bus with my friends, get a ride with some of my friends, or even go with my dad (if he doesn't mind). The tickets cost 72 dollars (+ 4.95 transaction fee from ticketek), and I am willing to pay for my ticket! The tickets are on sale this friday from 9 am so one of my parents will have to stay home from work to purchase them. (My guess is that they will sell out in under 15 mins :/) I really want to see them play and especially to see Louis Tomlinson as I have a major crush on him...... (even though he is 20 :/). I f I do get to go I would also want to get clothes, bangles, cd's for them to sign (All songs I have are online off itunes) etc. that have One direction all over them (: (on ebay?? not at the concert as its usually 40/ 50 dollars for a jumper etc. at the concert and 20 dollars off ebay (:! ) All help is thoroughly appreciated!!!

Thx in advance!!!
