Answer 1

Answer:

1.(b) 64000

2.(b) 12 X (7 + 9) = (12 X 7) + (12 X 9)

Answer 2

Answer:

1. 64000
2. 12 X (7 + 9) = (12 X 7) + (12 X 9)
3. 8
4. Multiplicative property of 1
5. (15 X 9) X 14 = 15 X (9 X14)

Step-by-step explanation:

1. Whenever multiplying ✖ the number have 0 at their end .Just multiply the number like here 8×8 = 64 ... and total number of 0 we're 3 so 6400
2. According to distributive property a × (b + c) = (a×b) +(a×c)
3. on Multiplying 24 and 7 we get [168] and the ones digit is 8
4. any no multiplied by 1 is the number itself
