Certainly! To express the square root of 21 in exponent form, we use the property of exponents that states [tex]\( \sqrt{a} = a^{1/2} \)[/tex].
So, [tex]\( \sqrt{21} \)[/tex] can be written as [tex]\( 21^{1/2} \)[/tex].
To further explain, the exponent 1/2 represents taking the square root of the number. Hence, raising 21 to the power of 1/2 gives us the square root of 21.
Thus, [tex]\( \sqrt{21} = 21^{1/2} \)[/tex].
When calculated, this gives approximately 4.58257569495584.
