This means we need to determine which number, when multiplied by itself three times (cubed), gives 216.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 1: Understanding Cube Roots<\/h3>\n\n\n\n<p>The cube root of a number xxx, denoted x1\/3x^{1\/3}x1\/3, is a value that, when raised to the third power (multiplied by itself three times), gives xxx. Mathematically, this can be expressed as:x3=ysuch&nbsp;thaty3=x\\sqrt[3]{x} = y \\quad \\text{such that} \\quad y^3 = x3x\u200b=ysuch&nbsp;thaty3=x<\/p>\n\n\n\n<p>For example, 83=2\\sqrt[3]{8} = 238\u200b=2 because 23=82^3 = 823=8.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Prime Factorization of 216<\/h3>\n\n\n\n<p>To simplify 2161\/3216^{1\/3}2161\/3, we begin by finding the prime factorization of 216. We divide 216 by the smallest prime numbers until we reach a product of primes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>216\u00f72=108216 \\div 2 = 108216\u00f72=108 (since 216 is even, we start with 2).<\/li>\n\n\n\n<li>108\u00f72=54108 \\div 2 = 54108\u00f72=54.<\/li>\n\n\n\n<li>54\u00f72=2754 \\div 2 = 2754\u00f72=27.<\/li>\n\n\n\n<li>27\u00f73=927 \\div 3 = 927\u00f73=9 (since 27 is divisible by 3).<\/li>\n\n\n\n<li>9\u00f73=39 \\div 3 = 39\u00f73=3.<\/li>\n\n\n\n<li>3\u00f73=13 \\div 3 = 13\u00f73=1.<\/li>\n<\/ul>\n\n\n\n<p>Thus, the prime factorization of 216 is:216=23\u00d733216 = 2^3 \\times 3^3216=23\u00d733<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Applying the Cube Root<\/h3>\n\n\n\n<p>Now, we take the cube root of both sides of the equation 216=23\u00d733216 = 2^3 \\times 3^3216=23\u00d733:2163=23\u00d7333\\sqrt[3]{216} = \\sqrt[3]{2^3 \\times 3^3}3216\u200b=323\u00d733\u200b<\/p>\n\n\n\n<p>Since a33=a\\sqrt[3]{a^3} = a3a3\u200b=a, we can simplify this as:2163=2\u00d73=6\\sqrt[3]{216} = 2 \\times 3 = 63216\u200b=2\u00d73=6<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Final Answer:<\/h3>\n\n\n\n<p>Thus, 2161\/3=6216^{1\/3} = 62161\/3=6.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation of Cube Roots:<\/h3>\n\n\n\n<p>Taking the cube root is a way to reverse cubing a number. Just as the square root is the reverse of squaring a number, the cube root is the reverse of cubing. This is why simplifying cube roots often involves factoring the number into powers of prime numbers. The cube root of a number is particularly useful in geometry and algebra when dealing with volumes of cubes and cubic equations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Simplify.216^1\/3 The Correct Answer and Explanation is: To simplify 2161\/3216^{1\/3}2161\/3, we are asked to find the cube root of 216.
