Question

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

hint Hint:

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.
