Answer:
4⋅(a⋅2)
2⋅(4⋅a)
8a
Step-by-step explanation:
(4⋅a)⋅2
4⋅(a⋅2) This is the same by the associative property of multiplication
2⋅(4⋅a) This is the same by the associative property of multiplication and the communicative property of multiplication
4⋅2⋅a⋅2 This brings in an extra 2 so it is not the same.
8a 4*2 = 8 so this is the same
4⋅2+a⋅2 This is the not the same 8+2a is not the same as 8a
(10 Aus) x <u>(1 NZ / 0.8262 Aus)</u> x <u>(1 Brit / 3.1517 NZ)</u> x <u>(1 US$ / 0.6536 Brit)</u> =
(10) / (0.8262 x 3.1517 x 0.6536) = <em>US$ 5.87</em> (rounded)
Notice that each of the underlined fractions in the top line is equal to " 1 ".
So they change the units of the " 10 AUS " but they don't change its value.,
