Answer:

Only natural numbers (i.e., non-negative integers) can be the exponents of variables in a polynomial.

Step-by-step explanation:

The exponent of variables in a polynomial should be natural numbers (0, 1, 2, 3, \dots.)

  • \sqrt{2\, x} is equal to \sqrt{2}\, x^{1/2}. In this expression, x is the variable. Its exponent is 1/2, which isn't a natural number.
  • On the other hand, \sqrt{2}\, x is equivalent to \sqrt{2}\, x^{1}. The exponent of variable x is 1, which is indeed a natural number.

\sqrt{2\, x} isn't a polynomial because the exponent of variable x isn't a natural number. On the other hand, \sqrt{2}\, x is indeed a polynomial over the set of real numbers.

A user’s password to access a computer system consists of 3 letters followed by 2 digits. How many different passwords are possi
Vesnalui [34]

Answer:

26*26*26 = 17576 ways to select 3 letters

10*10= 100 ways to select 2 numbers

So then the total number of ways are:

26^3 *10^2 = 1757600 possible ways

Step-by-step explanation:

For this case we assume that we have 26 letters from A to Z and 10 numbers from 0 to 9 .

And we want to calculate the number of possible passwords possible if the password consists of 3 letters followed by 2 digits.

And for this case we can use the multiplication principle of combinatories, since we don't have any restriction about the letters of the numbers we can have repetition of letters or numbers.

For the number of possible letters:

26*26*26 = 17576 ways to select 3 letters

10*10= 100 ways to select 2 numbers

So then the total number of ways are:

26^3 *10^2 = 1757600 possible ways

sum of half a number and 4 means
(x/2)+4
result is -16

(x/2)+4=-16
minus 4 both sides
x/2=-20
times 2 both sides
x=-40
the number is -40
