2-2+7(√10-√3)/(√10+√3)(√10-√3)-√10+√3=7(√10-√3)/(10-3)-√10+√3= =√10-√3-√10+√3=0

8^1/3= (2^3)^1/3=2 16^1/4=(2^4)^1/4=2 7*( (10^1/2 -3^1/2) ------------------------------ = (10^1/2)^2 -(3^1/2)^2 7(10^1/2 -3^1/2) ---------------------- = 10 -3 7(10^1/2 -3^1/2) ---------------------- = 7 10^1/2 -3^1/2 100^1/4=(10^2)^1/4= 10^1/2 9^1/4= (3^2)^1/4=3^1/2 Собираем в кучку 2-2+10^1/2 -3^1/2 -10^1/2 +3^1/2=0
