When multiplying powers with the same base, simply add the exponents. For example,$3^2 \times 3^4 = 3^6$

When dividing powers with the same base, simply subtract the exponents. For example,$3^2 \div 3^4 = 3^{-2}$

7. anonymous

Any number raised to the exponent 0 equals 1. For example,$3^0 = 1$

8. anonymous

And to change the sign of an exponent, take the reciprocal of the power. For example,$3^{-2} = \frac{ 1 }{ 3^2 }$

That should be everything you need.

sorry i am not understanding

Take the second box on your question. It is a multiplication of powers with the same base. So add the exponents. What do you get?

12. anonymous

Look at the first example I did and apply that to your question.

i am not sure i am horrible at exponites

14. anonymous

It's not difficult, all you need is to be able to add and subtract.

In the second box, the base is 5. What are the two exponents?

16. Testing123guest

3 and -1

17. anonymous

Good. Add those two exponents together. What do you get?

18. Testing123guest

2

Terrific. So$5^3 \times 5^{-1} = 5^2$See how it works. Easy as pie.

Now, I would leave the 3rd box the way it is and simplify the 4th box. Look at my 4th example above. What happens when you take the reciprocal of a power?

Hello?
