C= 2(racine de)105 x (racine de) 51

(divisé par)

3 (racine de) 34

D= (3racine de 2 – 1)au carré – 4 (racine de 2 + 4)au carré

J’espere que ‘racine de’ veut dire ‘square root’ et que ‘au carre’ veut dire ‘squared’ (ecrit ^2).

C = 2 sqrt(105) * sqrt(51) / 3 sqrt(34)

= 2 sqrt(7*3*5*17*3) / 3 sqrt(17*2)

= (2/3) * 3 sqrt(7 * 5 / 2)

= 2 sqrt(35) / sqrt(2)

= sqrt(70)

= racine de 70.

D = (3sqrt(2) – 1)^2 – 4(sqrt(2) + 4)^2

= 9*2 + 1 – 6sqrt(2) – 4(2 + 16 + 8sqrt(2))

= 19 – 6sqrt(2) – 72 – 32sqrt(2))

= – 53 – 38sqrt(2)

= – 53 – 38 racine de 2.
