Question

Verify a x (b + c) = (ax b ) + ( a x c) where a = -11/4, b=-3/5, c=2/15

Answer 1

Answer:

a x (b + c) = (ax b ) + ( a x c)

:-) ab+ac = ab+ac

:-) Hence, it is proved

Step-by-step explanation:

1. ab+ac = ab+ac
2. -11/4(-3/5)+[-11/4(2/15)] = -11/4(-3/5)+[-11/4(2/15)]
3. -33/20+[-22/60] = -33/20+[-22/60]
4. -33/20-22/60 = -33/20-22/60
5. -33/20+33/20 = -22/60+22/60
6. (-33+33)/20 = (-22+22)/60
7. 0/20 = 0/60
8. 0 = 0
