Answer:

\frac{m^{14}}{t^{10}}

Step-by-step explanation:

To evaluate or simplify expressions with exponents, we use exponent rules.  

1. An exponent is only a short cut for multiplication. It simplifies how we write the expression.

2. When we multiply terms with the same bases, we add exponents.

3. When we divide terms with the same bases, we subtract exponents.

4. When we have a base to the exponent of 0, it is 1.

5. A negative exponent creates a fraction.

6. When we raise an exponent to an exponent, we multiply exponents.

7. When we have exponents with parenthesis, we apply it to everything in the parenthesis.

We will use these rules to simplify.

(m^7t^{-5})^2 = m^{14}t^{-10} = \frac{m^{14}}{t^{10}}

Answer:

Onaje is correct.

Step-by-step explanation:

To start, total up how many shirts we have, and multiply them by <em>t</em>. Since they are the same price, we now have a total for how many shirts they bought. This proves the second and third equations that they wrote. If you take the easy way and just add them, you'll still have 25<em>t</em>, making Onaje's expression correct.

EDIT: Just saw you need why it's incorrect for Paula, just hold on.

So for Paula, it's simple why she is incorrect. If you look at the third equation she wrote, she's adding 25 to 2t, which is completely incorrect, and will come up with a different result than 16t + 9t.

Hope this helps.

Hi there!

Looking at the graph, we can see zeroes at x = -4, 0 (bounce, degree of 2) and 3. The graph is also face up, so it is positive. We can write an equation in factored form:

f(x) = x²(x + 4)(x - 3)

Find the equation of g by translating each zero left. The new zeros would be:

x = -6, x = -2, and x = 1

Write the polynomial:

g(x) = (x + 2)²(x + 6)(x - 1)

So, we need to figure out how much times the body size of the flea it can jump. First, we need to figure out the size of the flea: <em>2^-4=0.0625</em>

Now that we have the size of the flea, we need to figure out how high it can jump: <em>2^3=8</em>

After we figure out the size of the flea, we need to divide 8 by .0625 because it is inverse operations to multiplication: <em>8/.0625=128</em>

Answer: The flea can jump 128 times higher than it's body size.
