Question

Square root of 26 in simplify radical form?

Answer 1

We know that

the number $26$ is equal to
 $(2*13)$
has no square factors
so
$\sqrt{26}$ 
cannot be simplified.

therefore

the answer is
The simplified form of the radical number given,
$\sqrt{26}$, is already itself.

Answer 2

The simplified version or form of the radical number given, square root of 26, is already itself. This is because this radical is already in its simplest form. We can no longer factor out 26 to give us any two or more numbers that can be expressed in simpler radical form. Note that the factors of 26 are 2 and 13 only.
