Square roots. Woohoo. Want to check some work I did.
1. Perform indicated operations
3sqrt[3]+2sqrt[27]sqrt[12]
3sqrt[3]+2sqrt[3*9]sqrt[2*6]
3sqrt[3]+3*2sqrt[3]2sqrt[3]
3sqrt+6sqrt[3]2sqrt[3]
= 7sqrt[3]
2.Simplify
sqrt[49x^12y^4z^8]
= 7x^6y^2z^4
3.Multply
(8sqrt[6]+3sqrt[2])(4sqrt[6]5sqrt[2]
32sqrt[36]40sqrt[12]+12sqrt[12]15sqrt[4]
32*640sqrt[12]+12sqrt[12]15*2
192  28sqrt[12] 30
162  28sqrt[12]
or am i missing a step?
19240sqrt[4*3]+12sqrt[4*3]30
16240*4sqrt[3]+12*4sqrt[3]
162160sqrt[3]+48sqrt[3]
162 128sqrt[3] which I think turns into 162 56sqrt[3]

Can someone check these for me? Please? Use halfangle identity to find the exact value of cos165 degrees. (1/2) sqrt(2+sqrt(3)) Write the equation 2x+3y5=0 in normal form. (2sqrt(13)/13)x (3sqrt(13)/13)y+ (5 sqrt (13)/13) = 0
