Question

4. Difference of two perfect cubes is 189. If the cube root of the smaller of the two numbers is 3. find the cube root
of the large number​

Answer 1

Step-by-step explanation:

So, let's consider the cube root of the larger no as x

So,

x^3 - 3^3 = 189

x^3 - 27 = 189

x^3 = 189 + 27

x^3 = 216

x = cu. root of 216

x = 6

Therefore, the cube root of the larger no. is 6
