Question

difference of two perfect cubes is 387 if tge cube root of the greater of two numbers is 8 find tge cube root of the smaller number

Answer 1

125

is the another number

Answer 2

Let x be the greater number and y be the smaller one. 

ATQ, cube root of greater number is 8. So ∛x= 8 
x= 8³
x=512

Also the difference of two perfect cube = 387

⇒ 512- y = 387
⇒ y= 512 - 387
⇒ y= 125

So the cuberoot of smaller number is ∛125= 5

Answer=5
