To get our answer, can either work backwards, or use another viable strategy, giving random operations until we find the correct answer.
40/10/4*(8/2-3)*5^2 = 25
The second problem is much simpler. There is no exponent in this problem, therefore making it much easier to complete.
(9+5)+2+4+30-2+3 = 51
Hope this helps. :)
