5/9 OR 0.5 repeating.. here's how: "radical 5 over 3" times "radical 5 over 3" (because squaring means to multiply a number by itself) is "radical 25 over 9". this is not complete: the square root of "25" is "5" so the final answer is 5/9. "5" divided by "9" is "0.5 repeating".
4 radical 3 is about 6.92820323
It could be written as 28 divided by radical 3. However, you will normally be required to rationalise the denominator which brings you back to 28 radical 3 divided by 3.

The dividend is the number located under the radical in a division problem 12 divided by 3 = 4 the quotient would be 4 (the number above the radical) and the dividend would be 3
