Simplifying cube roots
WebbSimplifying a Square Root or a Cube Root of a Whole Number The key idea in simplifying a radical is factoring. To simplify the square root of a whole number: 1. Factor the number, trying to find perfect square factors. 2. Rewrite each factor under its own radical symbol. 3. WebbIf so, then you simply need to simplify the square root of the answer.

In addition, I simplify 125 and simplify the cube... chirowell azWebbA cube root is simplified if it does not contain any factors that can be written as perfect cubes. The idea is to identify the largest cube factor of the radicand and then apply the product or quotient rule for radicals. As an example, to simplify 3√80, notice that 80 is not a perfect cube. However, 80 = 8 ⋅ 10 and we can write, chirowerkstattWebbThe alternate way is to go into rational exponents so if you have the cube root of the square root of (x-5) =2, you get ((x-5)^(1/2))^1/3 = 2, power to power requires multiplication, so (x-5)^1/6 = 2, opposite of 1/6 is 6 in exponent, so (x-5)^(1/6*6)=2^6, x-5=64, x=69. chirowerks scott kocisWebbHow to Simplify Algebraic Cube Roots?
