Question

Q) [-1]×[-1]×[-1]×.......taken 25 times
= -1
How the answer is -1 please tell me

Answer 1

Bonjour!

As, we can see that (-1) is multiplied 25 time which is odd number.

So, multiplying a negative number odd time we get negative number but if we multiple it even times we will get positive number.

And multiplying 1 many times will always give 1 only.

Hope this helps...:)

Answer 2

see, if you multiply 1 with 1
answer will be 1 and if you multiply (-1) with (-1) answer will be 1 as (-1) is multiplied only twice which is an even no.
if you multiply (-1)×(-1)×(-1) answer will be (-1) because (-1) is multiplied 3 times
which is an odd no.
here (-1) is multiplied 25 times which is an odd number
therefore answer will be (-1)
hope this helps
