Question

(i) 673 x 9 + 673
3. Verify:
(1) 37 x {8 + (-3)} = 37 x 8 + 37 (3)
(ii) (-82) * {(-4) + 19} = (–82) × (-4) + (-82) x 19
(iii) {7 - (-7)} x 7 = 7 * 7 - (-7) x 7
(iv) {(-15) – 8} *-6 = (-15) x (-6) - 8 (-6)



​

Answer 1

Step-by-step explanation:

(I) =37*{8+(-3)}=37*8+37*3

LHS=37*-5=296+111

=-185=407

LHS not equal RHS

Answer 2

$\huge \cal \colorbox{pink}{AN§WER}$

37 x {8 + (-3)} = 37 x 8 + 37 x – (3)

L.H.S. = 37 x {8 + (-3)}

= 37 x {8-3}

= 37 x {5}

= 37 x 5

= 185

R.H.S. = 37 x 8 + 37 – 3

= 37 x (8 – 3)

= 37 x 5

= 185

Hence, L.H.S. = R.H.S.

(-82) x {(-4) + 19} = (-82) x (-4) + (-82) x 19

L.H.S. = (-82) x {(_4) + 19}

= (-82) x {-4 + 19}

= (-82)x {15}

= -82 x 15

=-1230

R.H.S. = (-82) x (-4) + (-82) x 19

= -82 x (-4 + 19)

= -82 x 15

=-1230

Hence, L.H.S. = R.H.S.

{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.

{(-15) – 8} x -6 = (-15) x (-6) – 8 x (-6)

L.H.S. = {(-15)-8} x-6

= {-15-8} x-6

= {-23} x-6

= -23 x- 6

= 138

R.H.S. = (-15) x (-6) – 8 x (-6)

= -6 x (-15-8)

= -6 x -23

= 138

Hence, L.H.S. = R.H.S.
