Question 290056
6(sqrt7/sqrt4)+3(sqrt28)-10(sqrt1/sqrt7) [factor sqrt28=sqrt4*7=2sqrt7, sqrt4=2 &sqrt1=1.
6(sqrt7)/2+3*2(sqrt7)-10/(sqrt7)
3(sqrt7)+6(sqrt7)-10/(sqrt7) find a common denominator (sqrt7).
[3(sqrt7)(sqrt7)+6(sqrt7)(sqrt7)-10]/(sqrt7)
[3*7+6*7-10]/(sqrt7)
[21+42-10]/(sqrt7)
[63-10]/(sqrt7)
53/(sqrt7) ans.
