Write [tex]\sqrt{21}[/tex] in exponent form.

Sagot :

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.
