Question

81×[7 + (-4)] = [81×7] + [81×(-4)]​

Answer 1

Step-by-step explanation:

given that

L.H.S

$= 81 \times (7 + ( - 4))$

R.H.S

$= (81 \times 7) + (81 \times ( - 4))$

step 1) solve L.H.S.

$81 \times (7 - 4) \\ 81 \times 3 \\ 243$

step 2) solve R.H.S

$(81 \times 7) + (81 \times - 4) \\ 567 + ( - 324) \\ 243$

hence L.H.S. is equal to R.H.S

Answer 2

Answer:

0

Step-by-step explanation:

81×[7+(-4)]=[81×7]+[81×(-4)]

81×3 =567+(-324)

243 =243

=243-243

=0
