Solution :-
Taking some example first,
→ (-1)²
→ (-1) * (-1)
since (negative) * (negative) = positive,
→ 1
and,
→ (-1)³
→ (-1) * (-1) * (-1)
→ {(-1) * (-1)} * (-1)
→ 1 * (-1)
→ (-1)
conclusion :-
- (-a)^n where n is an even number = a^n
- (-a)^n where n is an odd number = (-1)(a^n)
so,
→ (-1) × (-1) × (-1) × ______ × (-1) (15 times)
→ (-1)¹⁵
comparing with (-a)^n we get,
- a = 1
- n = 15 = odd number .
then,
→ (-a)^n
→ (-1)(a^n)
→ (-1)(1¹⁵)
→ (-1) * 1
→ (-1) (Ans.)
