i was unsure. If a problem is like 8at the power of 8 times 8at the power of 8 can it jus be written 8 at the power of 16?

quick question: exponents and powers, are the same thing right? like 5^2 is an example of bolth of them?

To answer R.W's question i think you are able to do that in that certain situation. If it is a different problem im not sure.

JS to CVDV:
No, the exponets and powers ARE NOT the same thing.
In the example that you gave me:
5^2:
the 2 is the exponet and the power is the whole probelm!

So NO! The exponet and power are NOT the same thing. Dont let that cnfuse you!

When you write a problem in exponential form, does it mean to write it fully, or with the little number at the top?
ex:
7x7x7x7
7^4

To answer R.W's question i am pretty sure you can do that. I a different problem, i am not exactly sure.

I am not sure what you are asking here. Are you asking if 8^8 is the equivalent of 8 x 2 = 16, it is not, it is equivalent to 8 * 8 * 8 * 8 * 8 * 8 * 8 * 8. If you are asking is (8^8)^8 is the same as saying 8^16 it is not. You would need 8 sets of 8 * 8 * 8 * 8 * 8 * 8 * 8 * 8, that would be 64 eights multiplied together or (8^8)^8 = 6.27710174 × 10^57

JS was pretty close. :-)

In the example given 5^2

5 is called the base

the ^2 is refered to as raise to the power of (in this case 2)

and

the small number two is the exponent.

Hope this clears this up for you. :-)
