Where is the index in a radical equation?
the index in a radical equation appears above and left of the root symbol and tells you what kind of root the radicand is.
What does a radical symbol refer to?
A radical symbol indicates taking a root. A radical symbol alone indicates a square root (or equivalently, raising to the 1/2 power). If there is a small superscript number just to the left of the radical, then that indicates which root to take (square root for 2, cube root for 3, forth root for 4, fifth root for five, etc). This means raising to the 1/x power, where x is the small superscript number to the left of the radical.
What is the radical approximation of radical 11?
There is no reasonable radical approximation for radical 11.
When you multiply a radical number with another radical number do the radical signs cancel each other out?
Not necessarily. If it is the same radical number, then the signs cancel out. Radical 5 times radical 5 equals 5. But if they are different, then you multiply the numbers and leave them under the radical sign. Example: radical 5 * radical 6 = radical 30
What is the conjugate of -a radical b?
