tried to solve the problem with foil method but i got confuse can someone help
1) (-7 + \sqrt{3x})( 4+ \sqrt{3x})
-7 * 4 = -28
-7 * \sqrt{3x} = -7\sqrt{3x}
\sqrt{3x} * 4 = 4\sqrt{3x}
\sqrt{3x} * \sqrt{3x} - does this equal \sqrt{3x} square or is it just 3x or leave it \sqrt{3x}
this is what...
ok so i was missing the little number am i doing question 2 correctly now?
[SIZE="4"]-3\sqrt[3]{-3} + [SIZE="4"]2\sqrt[3]{162} + [SIZE="4"]3\sqrt[3]{81}
[SIZE="4"]-3\sqrt[3]{-3} = [SIZE="4"]-3\sqrt[3]{3}
[SIZE="4"]2\sqrt[3]{162} = [SIZE="4"]6\sqrt[3]{6}
[SIZE="4"]3\sqrt[3]{81} =...
im not sure if I am doing these questions correctly can someone check it
1) [SIZE="4"]-3\sqrt[6]{3} - [SIZE="4"]2\sqrt[3]{192} - \sqrt[6]{320}
[SIZE="4"]-3\sqrt[6]{3} = [SIZE="4"]-3\sqrt[6]{3}
[SIZE="4"]2\sqrt[3]{192} = [SIZE="4"]6\sqrt[6]{3}
\sqrt[6]{320} = [SIZE="4"]2\sqrt[6]{5}...
