$\bf{{\underline{Explanation}}:}$

• When a number is squared, it means that the number itself is multiplied twice. When a negative integer is squared, it means that the negative integer is multiplied with the number itself twice. So, when a negative integer is multiplied by ‛ n ’ number of times, where ‛ n ’ is an even number, the product is always positive; where as, when a negative integer is multiplied by ‛ m ’ number of times, where ‛ m ’ is an odd number, the product will be negative itself..
