√32+√2 √2(√8+√50) =
⁻⁻⁻⁻⁻⁻⁻ =
√2
2√50+√72
⁻⁻⁻⁻⁻⁻⁻⁻⁻ =
√27-√12 2√2
⁻⁻⁻⁻⁻⁻⁻⁻ =
√3

Answer 1

√32+√2 √2(√8+√50)
-------------------------- =
√2

4√2+√2*√2(2√2+5√2)
-------------------------- =
√2

4√2+√2*√2(6√2)
-------------------------- =
√2

4√2+√2*6*2
-------------------------- =
√2

4√2+12√2
-------------- =
√2

16√2
-------------- = 16
√2

==============================================
2√50+√72
---------------- =
√27-√12 2√2

10√2+6√2
---------------- =
3√3-2√3*2√2

16√2
---------------- =
3√3-4√6

16√2.................3√3+4√6
----------------* ---------------=
3√3-4√6.............3√3+4√6


16√2(3√3-4√6)
-------------------=
27-96

48√6-64√12
-------------------=
-69

48√6-128√3
-------------------
-69
