Question

verify the property (a*(b-c) =a*b-a*c for each of the following where a = - 3 by 5 and b equal to 5 by 9 C = - 10 by 3​

Answer 1

SOLUTION

-3/5 [(5/9) - (-10/3)] = [(-3/5)*(5/9)] - [(-3/5)*(-10/3)]

-3/5 [(5/9) + (10/3)] = [(-3/5)*(5/9)] - [(3/5)*(10/3)]

[ since (-)×(-)=(+)]

(-3/5)(35/9) = (-1/3) - (2)

(-7/3) = (-7/3)
