Question

{7 – (-7)} × 7 = 7 × 7 – (-7) × 7​

Answer 1

Answer:

{7−(−7)}=7×7−(−7)×7{7−(−7)}=7×7−(−7)×7

Consider LHS ={7−(−7)}×7={7−(−7)}×7

It can be written as

={7+7}×7={7+7}×7

By further calculation

={14}×7={14}×7

=98=98

Similarly RHS =7×7−(−7)×7=7×7−(−7)×7

It can be written as

=7×7+7×7=7×7+7×7

By further calculation

=7×(7+7)=7×(7+7)

=7×14=7×14

=98=98

Therefore , LHS = RHS.
