A radical is an expression which implies the use of a root.
There are three components of a radical expression:
(i) The root "√".
(ii) The radicand √"a".
(iii) The degree or index of the radical
, when index of the radical is not shown then it understood to be a index of 2.
The index is the number used to indicate the degree of the root.
For the example
, 10 is the radican and the index is not shown so it understood is 2.
Step-by-step explanation:
Consider the provided statement.
If we lose electricity, then the data will be lost.
We are need to write the negation of the above statement.
First divide the whole statement in two parts
Let us consider p = We lose electricity and q = The data will be lost.
The symbol use for negation is tilde 


Represent T for true and F for False.
The required table is shown below:
p q 
F F F
F T F
T F T
T T F
Hence the required table is shown above.
