welshfella · Answer

the question confuses me!!

is that a subtraction of numbers  or a range of numbers?
1832 - 1392?

phi · Answer

it would help if you showed that there is an exponent
the problem is not
 1832 − 1392
it is
$$  183^2 − 139^2 $$
which you could show by writing it as
 183^2 − 139^2

phi · Answer

and they expect you to know how to "factor"
a^2 - b^2 into (a-b)(a+b)

welshfella · Answer

ah  - i see that makes sense
- yes use the '^'   for powers of numbers

thesmartone · Answer

Hint:

$a^2 - b^2 = (a+b)(a-b)$
