Hi! I'm a canadian student in america. Please help me on division of radicals =) 1.) 6√18 ÷ 12√40 2.) 8√19 ÷ 4√38 3.) 20√3 ÷ 5√ 3 4.) 42√ 6 ÷ 3√6 5.) -4√20 ÷ √2 6.) 1 / 2+√5 7.) 1 / 3-√11 8.) 3 / √3-1 9.) 5 / 2-√3 10.) 2 / 4-√14 thanks!

Hello, From #6 on I presume, that the denominators are sums(?): EB
