a).73²–27²=
b).110²– 90²=​

Answer 1

Step-by-step explanation:

From the commutative law of Subtraction [a-b = b-a]

Let,

a=36,b=−64

Left hand side (LHS),

=36–(−64)

=36+64

=100

Right hand side (RHS),

=(−64−36)

=−(64+36)

(Take out the –ve sign outside and do subtract smaller from bigger number)

=−100

By comparing LHS and RHS,

LHS



=RHS
