Question

4. Difference of two numbers, which are perfect cubes, is 189. If the cube to
of the smaller of the two numbers, is 3, find the cube root of the larger
number.
दो पूर्ण घन संख्याओं का अंतर 189 है। यदि इनमें से छोटी संख्या का घनमूल 3 है, तो बड़ी संख्या
का घनमूल ज्ञात कीजिए।

​

Answer 1

Answer:

We should do  find the cube of 3 and that is 27.

Now, add 27 to 189 = 27 + 189 = 216

Finally,  find the cube root of 216 and that is 6.

Therefore,  the cube root of the larger number is 6.

Answer 2

Difference of two perfect cubes is 189

Cube root of one of those is 3

Hence cube of 3 = 27

So one of those numbers is 27

The other number is 189+27 = 216

So the other number is 216

Cube root of 216 is 6

So 6 is the answer
