The answer is: The product [tex]4 \sqrt{7} [/tex] is a radical multiplied by an integer and the result is [tex]10.58[/tex] By definition, the set of integers has: negative numbers, positive numbers and zero. Radicals are also known as roots and can be written with the symbol: [tex] \sqrt[n]{}
[/tex] , where "n" is the index. Normally, when a radical is multiplied by an integer, you must simplify it, but in this case you can calculate the result by using your calculator.
