When you have fractions in the exponent, the denominator is the root and the numerator is the power on the number inside the root.

4^(1/7) = ⁷√(4)
4^(7/2) = √(4)^7
7^(1/4) = ⁴√(7)
7^(1/2) =  √(7)

Answer:

Radical form refers to a form of an algebraic expression in which we have a number or an expression underneath a radical.

Any algebraic expression involving exponents then, we can write it in radical form based on the fact that  x^{\frac{a}{n}} is equivalent to the nth root of x^a i.e,

x^{\frac{a}{n}} =\sqrt[n]{x^a}

Now, Consider the expression:

4^{\frac{1}{7}} = \sqrt[7]{4}

4^{\frac{7}{2}} = \sqrt[2]{4^7}

7^{\frac{1}{4}} = \sqrt[4]{7}

7^{\frac{1}{2}} = \sqrt[2]{7}
