Question 1062639
<pre><font size=4>
{{{(-3^"")(a^""+x)}}}, if a=8, x=-10

replace "a" by (8), and replace x by (-10)

{{{(-3^"")((8)^""+(-10))}}}

Combine the 8 and the (-10) as -2
[Subtract as in basic math and use the sign
of the larger]


{{{(-3^"")(-2^"")}}}

Now multiply the -3 by the -2

{{{"" + 6}}}

[A negative times a negative is a positive.]

Or just 

{{{6}}}
