Explicație pas cu pas:

√6/3√2 + 25/2√75 = √3/3 + 25/10√3 = √3/3 + 5/2√3 = √3/3 + 5√3/6

= 2√3/6 + 5√3/6 = 7√3/6

√3*7√3/6 = 21/6 = 7/2

____________

12/5√3 - √3/2 = 12√3/15 - √3/2 = 4√3/5 - √3/2 = 8√3/10 - 5√3/10 = 3√3/10 = √27/10

√27/10 : √27/27 = √27/10*27/√27 = 27/10

_____________

√48/5 + 2√3 = 4√3/5 + 10√3/5 = 14√3/5

14√3/5*1/√3 = 14/5

x = 7/2 - 27/10 + 14/5 = 35/10 - 27/10 - 28/10 = -20/10 = -2, numar intreg
