Using the Pythagorean Theorem, 

a² + b² = c²

c² = 8² + 8²

c² = 64 + 64

c² = 128

c = √128

c =8√2 (radical form) or  11.31 feet (nearest hundredth)

Answer: 11.31 feet

What is the radical expression
aleksandrvk [35]

The exponent in radical form is:

6^{\frac{3}{4}}

Further explanation:

The radical form is converted into exponential form by the following method

\sqrt[n]{x} = (x)^{\frac{1}{n}}

Given

(\sqrt[4]{6)^3} \\Converting\ into\ exponent\ form\\=[(6)^3]^{\frac{1}{4}}\\Exponent\ on\ exponent\ are\ multiplied\ to\ each\ other\\=(6)^{(3*\frac{1}{4})}\\=6^{\frac{3}{4}}

The exponent in radical form is:

6^{\frac{3}{4}}

Keywords: Radical form, Exponents
