Explicație pas cu pas:
a)
x√2 = 4√8 = 4*2√2 = 8√2
x = 8
b)
-2x√3 = 12√6
x = 12√6 : (-2√3) = -6√2
c)
4x = 8√2
x = 8√2 : 4 = 2√2
d)
-5x√5 = 10√125 = 10*5√5 = 50√5
x = 50√5 : (-5√5) = -10
e)
x : (2√3) = -√3
x = -√3*2√3 = -6
f)
2x : √6 = 2√3
2x = 2√3*√6 = 2√18 = 2*3√2 = 6√2
x = 6√2 : 2 = 3√2
g)
(x + 1) : √2 = √2
x + 1 = √2*√2 = 2
x = 2 - 1 = 1
h)
4x : 3√3 = 12
4x = 12*3√3 = 36√3
x = 36√3 : 4 = 9√3
i)
(2x + 1)*√3 = √3
2x + 1 = √3 : √3 = 1
2x = 1 - 1 = 0
x = 0 : 2 = 0
j)
10√6 : 5x = √3
10√6 = 5x√3
x = 10√6 : 5√3 = 2√2
