Question

Verify the following.
(i) 19* [5 + (-2)] = [19 * 5] + [19 * (-2)]
(ii) (-20) * [(-7) + (-11)] = [(-20) * (-7)] + [(-20) * (-11)

Answer 1

Answer:

(1) no

(2) yes

Step-by-step explanation:

1). 19*3=95+38

57#133 (not equal)

2). 20*18=140+220

360=360

Answer 2

Answer:

i

19*[5+(-2)] = [19*5] + [19*(-2)]

19[5-2] = [19*5] + [19*(-2)]

19*3=95+(-38)

19*3=95-38

57=57

hence,this is verified.

ii

(-20)*[(-7)+(-11)]=[(-20)*(-7)]+[(-20)*(-11)]

(-20)*(-7-11)={[-20*(-7)]+[-20*(-11)]}

(-20)*(-18)=(140+220)

360=360

hence,this is verified
