Question

simplifique
a) raiz de 50 ao quadrado
b) raiz de 108
c)raiz de 72
d)raiz de 216 a 3 .. me ajudem por favor

Answer 1

a - √50
50 | 2
25 | 5
 5 | 5
1 ---> √50 = √2x5x5 = √2x5² = 5√2

b - √108
108  | 2
54  | 2
27  | 3
9  | 3
3  | 3
1 -----> √108 = √2x2x3x3x3 = √2²x3²x3 = 2x3√3 = 6√3

c - √72
72  | 2
36  | 2
18  | 2
9  | 3
3  | 3
1 -------> √72 = √2x2x2x3x3 = √2²x2x3² = 2x3√3 = 6√2

d - ∛216
216  | 2
108  | 2 
54  | 2
27  | 3
9   | 3
3  | 3
1 ---------> ∛216 = ∛2x2x2x3x3x3 = ∛2³x3³ = 2x3 = 6
