Question
Verify: {7 – (-7)} x 7 = 7 x 7 – (-7) x 7
✓
Answer
{7 – (-7)}. x 7 = 7 x 7 – (-1) x 7
L.H.S. = {7 – (-7)} x 7
= {7 + 7} x 7
= {14} x 7
= 14 x 7
= 98
R.H.S. = 7 x 7 – (-7) x 7
=7 x 7+7 x 7
= 7 x (7 + 7)
= 7 x (14)
= 98
Hence, L.H.S. = R.H.S.
L.H.S. = {7 – (-7)} x 7
= {7 + 7} x 7
= {14} x 7
= 14 x 7
= 98
R.H.S. = 7 x 7 – (-7) x 7
=7 x 7+7 x 7
= 7 x (7 + 7)
= 7 x (14)
= 98
Hence, L.H.S. = R.H.S.
