Question

Rezolvati urmatoarele ecuatii,unde x apartine R \ {0}

a) x : (5v~21) =2v~7-------(v~ radical)
b) x: (-v~10) = 7v~5
c) x: (-v~6) = -7v~3
d) (-7v~10): x =7v~2
e) (-4v~21) :x = -2v~3
f) (-8v~) : x =4~5

Multumesc frumos de rezolvare <3​

Answer 1

Răspuns:

a) x: (5 v~21=2v~ => X=2v~7•5v~21

x=10•v~147

x=10•7v~3

x=70v~3
