WebThus, 128 ÷ 2 = 64 = 4 3 is a perfect cube. Hence the smallest number by which 128 should be divided to make a perfect cube is 2. (iii) 135. 135 = 3 × 3 × 3 × 5 = 3 3 × 5. Here, the prime factor 5 is not a triplet. Hence, we divide 135 by 5, so that the obtained number becomes a perfect cube. 135 ÷ 5 = 27 = 3 3 is a perfect cube. WebLet us understand it in a step-by-step procedure. Step 1: Find the prime factors of 1728. 1728 = 2x2x2x2x2x2x3x3x3. Step 2: Group the factors in a pair of three and write in the form of cubes. 1728 = (2x2x2)x (2x2x2)x (3x3x3) 1728 = 2 3 x2 3 x3 3. Step 3: Apply the cube root on both sides and take out the terms in cubes out of the cube root.
