Question

Would you classify the number 169 as a perfect square , a perfect cube , both or neither ?

hintHint:

Use the definition of perfect square and perfect cube and then classify.

The correct answer is: 169


    Complete step by step solution:
    Here we have the number = 169
    A perfect square is a number that can be expressed as a product of 2 equal integers.
    Here 169 space equals space 13 space cross times space 13
    A perfect cube is a number that can be expressed as a product of 3 equal integers.
    Here 169 = 5.5287 cross times 5.5287 cross times 5.5287
    Since  is not an integer, 169 is not a perfect cube.
    Hence 169 is a perfect square.
