Question 1 Find the cube roots of 27000 and 10648. Cube root of 27000 We see that 27000 = 2 × 2 × 2 × 3 × 3 × 3 × 5 × 5 × 5 = 23 × 33 × 53 = (2 × 3 × 5)3 = 303 Therefore, Cube root of 27000 = 30 Cube Root of 10648We see that 10648 = 2 × 2 × 2 × 11 × 11 × 11 = 23 × 113 = (2 × 11)3 = 223 Therefore, Cube root of 10648 = 22
