Question

(2to the power × 5to the power -1)×5to the power 2 =​

Answer 1

Answer

ANSWER WERE GOOGLED

Step-by-step explanation:

The main thing to notice is that there are an odd number of

(-2)'s and an even number of (-5)'s

Think of the (-2)'s grouped in pairs with one left over

(-2)*(-2) this is positive

(-2)*(-2) also positive

(-2) this is negative

So, you have (+) x (+) x (-) = (-)

 

---------------------------

What if it was +%28-2%29%5E67+ ?

You would pair these up the same way, so you'd have

a bunch of (+) x (+) x (+) . . . etc and one (-) left. that would

give you a minus result

--------------------

Back to your problem, then

+%28-2%29%5E5+=+-32+

and

+%28-5%29%5E2+=+25+

+-32+%2B+25+=+-7+
