A number&#8217;s cube root is a value that, when multiplied by itself three times, yields the original value.<\/p>\n<p>\u20183\u221a\u2019 represents the cube root symbol. In the case of square root, we simply used the root symbol, such as \u2018\u221a\u2019, which is also known as a radical.<\/p>\n<p>For example :<\/p>\n<p>The cube root of 27 is 3.
