Simplify the following equation completely. Write your answer in only positive exponents.
kotegsom [21]

Answer:

Appears to be A with a typo.

Should be \frac{3a^{12}*b^{3}}{4}

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.

\frac{12a^8b^{-7}}{(4a^{-2}b^{-5})^2}\\\\\frac{12a^8b^{-7}}{4^2a^{-4}b^{-10}} \\\\\frac{12}{16}*\frac{a^8}{a^{-4}}*\frac{b^{-7}}{b^{-10}}\\\\\frac{3}{4}*a^{8--4}*b^{-7--10}\\\\    \frac{3}{4}*a^{12}*b^{3}

A spinner has 5 sector's of equal size. The sectors are labeled 1,2,3,4, and 5. the spinner is spun twice.x is the number of tim
LuckyWell [14K]

Answer:

Because the sectors are of equal size, each sector has the same probability of happening.

So for every number, you have a probability of 0.2 of it appearing.

Because you have three odd numbers, the probability to land on an odd number on each spin is 0.6. You can also say that the probability to not have an odd number is 0.4.

So what is the probability to have 0 odd number in two spins?

What is the probability to have 1 odd number in two spins? You can have one odd number on the first or one odd on the second spin, that is why we add the probabilities.

What is the probability to have 2 odd numbers in two spins?

To verify if we did a good job, we add all the probabilities. We should get 1.

.

So to slide your bars, you slide them up to the number I gave you for each case.

Hope this helps!
