Question

verify that, (X + y) + z is equal to X + (y + z) for the following:-
1. x=3/7 ; y=2/5 ; z=1/2​

Answer 1

Step-by-step explanation:

it is obvious that when we multiply any number in anyway we got the same result

in this case it also happens here

first we have to add two numbers and then add the remaining number

suppose one is said to add (2 + 3 )+ 5 and and said to add 2 +( 3 + 5) we got the same result

here this is not necessary to prove that these will be equal your examiner will understand it

you just have to write LHS equals to RHS
