Question

prove that the following statements are false and give the reason. b.(76-6)-20=76-(6-20) d.(437-32)+48=437-(32+48) f.346-276=276-346​

Answer 1

Answer:

in b. while shifting brackets in RHS, we need to take -ve sign common.. so it should be (RHS) --> 76-(6+20).

Similarly, in d. (RHS)--> (437-(32-48)

And in f. both LHS and RHS have a difference of -ve sign.
