Question 760902
Note that if you have an odd number of negative
factors, you get a negative result:
(-) x (-) x (-) = (-)
{{{ -(-5)^3 = -( (-5)*(-5)*(-5) ) }}}
{{{ -( (-5)*(-5)*(-5) ) = -( -125 ) }}}
{{{ -( -125 ) = 125 }}}
--------------------
{{{ -7^2 = -( 7*7 ) = -49 }}}
Note that the minus in front is really a
shorthand for {{{ (-1)*7^2 }}}
If they showed it this way:
{{{ ( -7 )^2 }}} then you get
{{{ ( -7 )^2 = 49 }}}
