1). 4√2+√50= 2). 7-√3/√5+√4= Mohon di bantu !!!!

[tex] = 4 \sqrt{2} + \sqrt{25 \times 2} \\ = 4 \sqrt{2} + 5 \sqrt{2} \\ = 9 \sqrt{2} \\ \\ = \frac{(7 - \sqrt{3} )( \sqrt{5} - 2)}{( \sqrt{5 } + 2)( \sqrt{5} - 2) } \\ = \frac{7 \sqrt{5} - 14 - \sqrt{15} + 2 \sqrt{3} }{5-4} \\ = 7 \sqrt{5} - 14 - \sqrt{15} + 2 \sqrt{3}[/tex]
