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
This would be false because the difference in the highest and lowest numbers are 4.
Answer:
Step-by-step explanation:
B = { x, y } = { } , { x }, { y }, { x, y }
C = { 1, 2, 8 } = { } , { 1 }, { 2 }, { 8 }, { 1, 2 }, { 1, 8}, { 2, 8}, { 1, 2, 8}
. E = { a } ={ } , { a }
