Question

3√8 - 5√18 + 2√32 + 4√50

Answer 1

x = 3√8 - 5√18 + 2√32 + 4√50

x = 3√(4.2) - 5√(9.2) + 2√(16.2) + 4√(25.2)

x = 3√4√2 - 5√9√2 + 2√16√2 + 4√25√2

x = ( 3√4 - 5√9 + 2√16 + 4√25 )√2

x = ( 3.2 - 5.3 + 2.4 + 4.5 )√2

x = ( 6 - 15 + 8 + 20 )√2

x = ( 19 )√2

x = 19√2

x = 19 x 1,414

x = 26.866 => 26,87

x = 26,87
