<p>In<a>exponential form</a>, ∛865 is written as 865(1/3). The cube root is just the opposite operation of finding the cube of a<a>number</a>. For example: Assume ‘y’ as the cube root of 865, then y3 can be 865. Since the cube root of 865 is not an exact value, we can write it as approximately 9.545.</p>
