Can you explain to me how exponents work?

You can't combine exponents when the bases aren't the same.

  "x" is where the base is

For example:

    (the bases are x and y)

When an exponent is multiplied directly to another exponent, you multiply the exponents together.

For example:

 You can look at it like this:  

When a variable with an exponent is multiplied by a variable with an exponent, you add the exponents together.

For example:

When an exponent is divided by an exponent, you subtract the exponents.

For example:

When an exponent is negative, you move the number and its exponent to the other side of the fraction to make the exponent positive.

For example:

or

or

10x

step-by-step explanation:

the greatest common factor 30 and 20 is 10

5 is a common factor of 30 and 20 but 10 is also a factor and 10 is greater than 5 so 5 will definitely not be apart of our answer

now the most amount of x's you factor our is just 1 factor of 1

so 10x the gcf of the terms in the polynomial

the expected value of the random variable : 0, 1 and 2
