9It = sqrt(19 + 8sqrt(3)) - sqrt(19 - 8sqrt(3)); 3 - Dicamon

Question

9It = sqrt(19 + 8sqrt(3)) - sqrt(19 - 8sqrt(3)); 31B = sqrt((sqrt(2) - sqrt(3)) ^ 2) + sqrt(2); C= sqrt 17-12 sqrt 2 + sqrt 9+4 sqrt 2; 1= sqrt 6+2 sqrt 5- sqrt

Answer

A = = 4 A = <=0+h; 60 + 21 - 81 = 31n+61+ underline 512n-t61=21 C 3-2√2 + 2√2 1 = underline san- epsilon+1-51c+9N=d D = + 2 - r - snC + 9A = 0 = + 2√3 |r+8|| D D

Answer

A = sqrt(191813) - sqrt(197813); =116+2.4 sqrt 3 +3- sqrt 16-2.4 sqrt 3 +3 .; i = sqrt((4 + sqrt(3)) ^ 2) - sqrt((4 - sqrt(3)) ^ 2) = 4 + 13 - 4 + sqrt(3); 130=1 sqrt (2-13)^ 2 +
