(-mn8)3

would it be:
-m^3n^3164

(-mn8)3
= -24mn

Without carrots I have no idea where your exponents are.

how?I don't get this one?

Is this Sandro from Mrs.Pfeiffer's class?What grade are you in?

Leo is saying you need to use carets to show an exponent. As you have written it, (I'll rewrite it)
3*(8*-mn) = -24mn.

It is!I am in 9th grade!

(-mn8)^3 =

-m^3 n^3 8^3 =
-512*m^3 n^3

To simplify the expression (-mn8)^3, we need to apply the power of a product rule, which states that (ab)^n is equal to a^n * b^n. In this case, the expression is (-mn8)^3, so we need to raise each term inside the parentheses to the power of 3.

To solve this, we can separate the expression into three parts: -m^3, n^3, and 8^3. Let's simplify each part individually:

1. (-m)^3:
Since we have a negative sign in front of the variable 'm', we can write (-m)^3 as -m^3. This means that we take the cube of the absolute value of 'm' and place a negative sign in front of the result.

2. n^3:
The variable 'n' is not affected by the negative sign, so we can simply raise 'n' to the power of 3, resulting in n^3.

3. 8^3:
The number 8 raised to the power of 3 can be calculated by multiplying 8 by itself three times. Hence, 8^3 equals 8 * 8 * 8 = 512.

Now, let's put all the parts together:

(-mn8)^3 = -m^3 * n^3 * 8^3

Using our simplified values for each part, we have:

(-mn8)^3 = -m^3 * n^3 * 512

So, the simplified expression is -m^3 n^3 512.
