5+sqrt(19)+sqrt(147/8)
\(5+\sqrt{19}+\sqrt{\frac{147}{8}}\\~\\ 5+\sqrt{19}+\sqrt{\frac{147}{4*2}}\\~\\ 5+\sqrt{19}+\frac{1}{2}\sqrt{\frac{147}{2}}\\~\\ 5+\sqrt{19}+\frac{1}{2}\sqrt{\frac{147}{2}}\frac{\sqrt2}{\sqrt2}\\~\\ 5+\sqrt{19}+\frac{1}{2}\frac{\sqrt{147}}{\sqrt2}\frac{\sqrt2}{\sqrt2}\\~\\ 5+\sqrt{19}+\frac{1}{2}\frac{\sqrt{147*2}}{2}\\~\\ etc\)
That is not finished. If you go to the 'HOME' page on this site you will find a calculator.
Type in factor(147) then press equals, you will get the factors of 147 and you can simplify some more.
Please let guest asker finish this of him/her self.
