We have the following expression: (27x 4 - 18x 3 + 9x 2) ÷ 3x Dividing each term between 3x we have: 9x3 - 6x2 + 3x We can check the result: (9x3 - 6x2 + 3x) * (3x) = (27x4 - 18x3 + 9x2) Division OK. Answer: The result of the division is: 9x3 - 6x2 + 3x
The number of elements in a set is the cardinal number of the set
Here the number starts from 1 and continues till 94. So there are 94 numbers. Thus, the cardinal number of the set (1,2,3....94) is 94. The cardinal number of an empty set is 0.
