Question

va rog ajutati ma cât puteti de repede ​

Answer 1

A) 6v3

B) 10v5

C) 2^2 =4

D) 5^2 *v3 = 25v3

E) 7 * 3^2 = 7*9 = 63

F) V(2* 2^4 * 5* 5^2 * 7^2) = 4*5*7V(2*5) = 20*7v10 = 140v10

G) v(9*7 / 25*2) = (3/5)* v(7/2)

H) V(81*5 / 3*4) = (9/2)* v(5/3)

i) v( 3*16+2 / 16 )= v(50/16) =v(25*2 / 16)

= (5/4) * v2

V insemna radical
