x^8 / x ^4 =

x^2 is this right

-12x^4/3x = -4x^3 is this correct

yes it is if x does not equal to 0.

No. It isn't right. You subtract exponents when you divide different powers of the same number.

Your first answer is wrong; the second is correct. I did not notice the second question

And me I didn't notice the first one :)

To simplify the expression x^8 / x^4, you can subtract the exponents of x.

When you divide two powers with the same base, you subtract the exponents. Hence, x^8 / x^4 can be simplified as:

x^(8-4) = x^4

So, the correct simplified expression is x^4.

Now, let's simplify the second expression: -12x^4 / 3x.

To divide two terms with the same base, you subtract the exponents of x. In this case, the exponents are 4 and 1 respectively.

-12x^4 / 3x = -12/3 * (x^4/x^1)

-12/3 simplifies to -4.

Since x^4 / x^1 = x^(4-1) = x^3, the simplified expression becomes:

-4x^3

So, the correct simplified expression is -4x^3.
