Hello!

347: sqrt[sqrt(41) + 4sqrt(2)] * sqrt[sqrt(41) - sqrt(32)] = 

sqrt[(sqrt(41) + sqrt(32)) * (sqrt(41) - sqrt(32)) =

sqrt(41 - 32) = sqrt(9) = 3.


350: [sqrt(12 + sqrt(23)) + sqrt(12 - sqrt(23))]^2 = 

(12 + sqrt(23)) + (12 - sqrt(23)) + 2*sqrt[(12 + sqrt(23))*(12 - sqrt(23))] = 

24 + 2*sqrt[12^2 - 23] = 24 + 2*sqrt(121) = 24 + 2*11 = 24 + 22 = 46.


please post pictures directly if possible (there is the button on the toolbar)

Please ask if something is unclear.
