Question 1026153
{{{ (-1)^3 }}}
Think of this as -1 multiplied by itself 3 times:
{{{ (-1)*(-1)*(-1) }}}
-------------------
Here is a general rule:
If you multiply a negative number by itself
an EVEN number of times, the result is POSITIVE
-------------
If you multiply a negative number by itself
an ODD number of times, the result is NEGATIVE
-------------
This last rule is the one to follow in this case
{{{ (-1)*(-1)*(-1) = -1 }}}
---------------------
Hope this helps
