Answer:
Associative
Step-by-step explanation:
Associative property says the sum stays the same when the grouping of addends is changed.
a + (b + c) = (a + b) + c
Unless you have a text or a picture to make an inference about we can infer that cars would have wheels :)
((4+1)7)+((4+1)5)+((4+1)2)
(5*7)+(5*5)+(5*2)
5(7+5+2)
5(14)
*those are all versions of the expression, from rawest form to fully simplified

Answer:
Step-by-step explanation:
To get maximum product we need to optimize how we break down the numbers
Its obvious we don't want number 1 to be used as it won't change the product
Also we don't want to use big numbers, we can have four 5's instead of two 10's as it would give greater product, 5*5 > 10
<u>What is best number?</u>
- 2 and 3 are the smallest, 4 can be written as two 2's
- 5 = 2+ 3 and 2*3 = 6, so it is better to use 2's and 3's instead of 5
- 6 = 2+2+2, 2^3 = 8 and 6 = 3+ 3, 3^2 = 9, so it is better to use two 3's for 6
- 7 = 2+2+3, 2*2*3= 12, again 2's and 3's make greater product
<u>So the best is to break the number down to 2's and 3's</u>
- 23 = 2*10 + 3 ⇒ 2^10*3 = 3072
- 23 = 3*7 + 2 ⇒ 3^7*2 = 4374
As we see the maximum product we can get is 4374 with seven 3's and one 2.
<u>Hence the numbers are:</u>
