tentukan nilai dari akar 18-akar 32+5 akar2

=>> √ 18 - √ { 32 + 5 } √ 2
=>> √ 18 - √ 37 √ 2
=>> - √ 19 √ 2
=>> - √ 38

[tex] \sqrt{18} - \sqrt{32} + 5\sqrt{2} \\ = \sqrt{9.2} - \sqrt{16.2} + 5\sqrt{2} \\ = \sqrt{3^2.2} - \sqrt{4^2.2} + 5\sqrt{2} \\ = 3\sqrt{2} - 4\sqrt{2} + 5\sqrt{2} \\ = 4\sqrt{2} [/tex]
