GIVEN :

The cube of number is 8 times the cube of another number if the sum of cubes

of numbers is 243 then what is the difference of the numbers?

to find :

what is the difference of the numbers?

solution :

• (X)3=8(y)3

• (X)3+(y)3=243

• (X)3=8(y)3

• 8(y)3+(y)3=243

• 9y3=243

• Y3-243-9

• Y3=27

• Y=3

• numbers are

• Y3=3^3=27

• 8y3-8×27-216

• Difference of the numbers are 216-27-189
