Question

calcule

√50 + √98 =?



√12 + √75 + √108 = ?

Answer 1

raiz de 50 = 2 x 25= 5 raiz de 2 
raiz de 98 = 2 x 49= 7 raiz de 2

(5 raiz de 2) + (7 raiz de 2 )= 12 raiz de 2 

raiz de 12 = 3 x 4 = 2 raiz de 3
raiz de 75= 3 x 25 = 5 raiz de 3
raiz de 108 = 3 x 36 = 6 raiz de 3

(2 raiz de 3 )+ (5 raiz de 3) + (6 raiz de 3) = 13 raiz de 3
