HOPE IT HELPS ☺️.

Answer 2

Let's assume the number as x

According to Question,

x^3 - 2 = 25

=> x^3 = 25 + 2

=> x^3 = 27

=> x = ³√27

=> x = 3

Hence, the required number is 3


Check -
______

LHS = x^3 - 2 RHS = 25

= (3)^3 - 2

= 27 - 2

= 25

As, 25 = 25

Hence, LHS = RHS

Hence, it is verified that the solution is correct
