Question

The difference of two perfect cubes is 386. If the cube root of the smaller of the two number
is 7, then the cube root of the larger number is
​

Answer 1

ans)27

Explanation: (^3= cubed)

okay so take the larger number as x^3

and the smaller number is 7^3

so

x^3 - 7^3

x^3 - 343 (because the cube of 7 is 343) = 386

x^3=386+343

x= $\sqrt{729$

=27

so the larger number is 27

hope it helps you!
