Step-by-step explanation:-
first write the equation so that you'll emit minor mistakes of writing wrong digits.
subtract 8 and 5 , which will give us result as 3
open the brakets that contains 3.
multiply 3 with 1 which will result 3.
open the brakets of 3.
to make it easy to understand I have converted it into fraction form.
simplify 12 which is contained in numerator.
as we can see after converting into fraction 3 is common both in numerator and denominator. So cancel ir.
we no longer need the fraction as 3 is canceled.
multiply 2 with 2 which will result 4.
finally after subtracting 25 and 4 , we got our answer as 21.
Rule applied:-
B : bracket
O : on/off
