Answer 1

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

Answer 2

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
