To write the difference of ( z ) and 8 as an expression, you would subtract 8 from ( z ). This can be expressed mathematically as ( z - 8 ). This expression represents the value obtained when 8 is taken away from ( z ).
The index in a radical indicates the degree of the root being taken. For example, in the radical expression (\sqrt[n]{a}), (n) is the index, which specifies that you are finding the (n)th root of (a). If the index is not written explicitly, as in (\sqrt{a}), it is understood to be 2, indicating a square root. The index helps determine how many times the number must be multiplied by itself to achieve the value under the radical.
The expression (2C3) represents the number of combinations of 2 items taken 3 at a time. However, since you cannot choose more items than are available, (2C3) is equal to 0. In mathematical terms, it can be expressed as ( \frac{2!}{3!(2-3)!} ), which is undefined due to the factorial of a negative number. Thus, (2C3 = 0).
6 feet under is an expression meaning someone has died. It is taken from the fact that the standard depth of a grave is 6 feet.
