By what smallest number 5184 be(a) multiplied(b) divided, so that the resulting number becomes a perfect cube.9. What is the smallest number by which 13500 should be multiplied so that the product is a perf10. What is the smallest number by which 27648 should be divided so that the quotient is a perfedCube RootsyouThe cube root of a number x is represented as Vx.The symbol x stands for cube root of.Thus, the cube root of8=28= 32x2x2 =2Similarly,964 = 34x4x4 = 4So, we can say thatif n = mº, where n is a natural number, then m is the cube root of n.Cube Root by Prime Factorisation MethodIn this, we can apply this method by following steps:Step 1: Factorise the given number by prime factors.Step 2: Make groups in triplets, each having 3 similar factors.Step 3: Take one number from each group and multiply together.Step 4: The product is the cube root of the given number.
