Answer 2

ii)Cube root of 2197, 3√2197 = 13

Let 3√2197 = x, then 2197 = x3. Now, we need to find here the value of x. The fastest method to find the value of the cube root of a four-digit number, 2197, is the estimation method. Although, we will also look into the prime factorisation method for better understanding.
